First of all, there are some Pokemon mentioned here that cannot deal with Lucario at all, depending on its moveset. For example:
Against stall teams, its going to need to find a set up opportunity against the phazers stall teams have, as well as break past Unaware Clefable, against more balanced teams, its going to need to break past Aegislash, Gliscor, Landorus-T, Mega Venusaur, Togekiss (?), Zapdos (?), Gyarados (?), Slowbro, Sableye, and Conkeldurr, and against offensive teams it needs to find set up opportunities against a HO style team, as well as avoid Azumarill, Gengar, and Aegislash.
One of the nice things with Lucario is that it can break past common stall cores with just its STABs. With Close Combat / Iron Tail / Extremspeed / Swords Dance, it can OHKO Unaware max HP / max Def+ Clefable after SR, do 72% minimum to max HP / max Def+ Mega Venusaur, and 76% minimum damage against 252 HP / 184 Def+ Gliscor. As for Azumarill, either Iron Tail or Earthquake are enough to do the job:
- +2 252+ Atk Life Orb Lucario Earthquake vs. 252 HP / 0 Def Azumarill (CB): 333-393 (82.4 - 97.2%) -- 62.5% chance to OHKO after Stealth Rock
- +2 252+ Atk Life Orb Lucario Iron Tail vs. 252 HP / 0 Def Azumarill (CB): 499-589 (123.5 - 145.7%) -- guaranteed OHKO
- +2 252+ Atk Life Orb Lucario Earthquake vs. 0 HP / 0 Def Azumarill (Belly Drum): 333-393 (97.9 - 115.5%) -- guaranteed OHKO after Stealth Rock
- +2 252+ Atk Life Orb Lucario Iron Tail vs. 0 HP / 0 Def Azumarill (Belly Drum): 499-589 (146.7 - 173.2%) -- guaranteed OHKO
And even if the CB Azumarill wants to revenge kill Lucario with Aqua Jet after a Close Combat Defense drop, +2 Extremspeed does ~72% to 252 HP Azumarill, so with just a tiny bit of previous damage and SR up, it can be OHKOed.
Same goes for Aegislash, which is easily OHKOed by +2 Eearthquake.
However, Lucario obviously has to choose between Iron Tail and Earthquake, so we have to make sure that whatever threat Lucario can't cover with our move of choice will be covered by the CAP.
Now, on to DLC' questions:
1. What support does Lucario require to sweep or significantly weaken an opponent's team?
As others have already mentioned, Lucario needs Ground-types weakened, namely Hippowdon, Garchomp, Landorus-T, Gliscor, Landorus, and Choice Scarf Excadrill. Fairy-types are not such a big problem, as Lucario can easily deal with them if it chooses so, but it would be good for the CAP to have the ability to at least threaten them 1 on 1 if Lucario forgoes Iron Tail for Earthquake, or even Ice Punch, so that Lucario can have some versatility when taking part in this core, and not always be forced to run Iron Tail. Good offensive checks to Lucario other than fast Ground-types are Conkeldurr, Terrakion, Keldeo, Gengar, and Gyarados, but all of them except from Gengar and Terrakion have to be in tip top shape to handle Lucario. The CAP should fare well against most of those Pokemon that Latias can't handle, meaning Gengar, Gyarados, and somewhat Conkeldurr and Terrakion (which Latias can OHKO with Psyshock but struggles to switch in, as Knock Off OHKOes, though if Lucario stays in as Conkeldurr uses Knock Off then the game is most likely over). As for defensive checks other than Ground-types, we have Aegislash, Zapdos, Sableye, and Slowbro, and Fairy-types / Mega Venusaur if Lucario lacks Iron Tail. Latias can switch into Zapdos and Slowbro, but struggles to get past Zapdos, and hates switching into Thunder Wave from Slowbro, so if the CAP could threaten those Pokemon in some way it would be nice, but not a must. However,
the CAP should definitely be able to threaten and switch into Aegislash, a huge threat to both Lucario and Latias. Something to handle Sableye would be nice as well, as both Latias and Lucario can't get past it.
2. What can Latias do to allow Lucario to sweep an opponent's team?
The best that Latias can do to allow Lucario to sweep is attract Pokemon that Lucario can set up on, so that Lucario comes in with a double switch against those Pokemon. Such Pokemon are Chansey, Heatran, Bisharp, Tyranitar, non-Scarf Excadrill, Ferrothorn, Sylveon, and Clefable (if Lucario has Iron Tail in the case of the last two). This way, the opponent has to choose between losing a vital member of his offensive / defensive core, or getting swept / weakened by Lucario. Latias can also give Lucario a second chance to sweep with Healing Wish, if Lucario is too weakened to pull it off on its own, but Lucario will rarely find time to set up twice. Other than that, there is not much that Latias can do for Lucario to prepare its sweep though.
3. What are Lucario and Latias unable to defeat together? What can CAP 18 do to cover those weaknesses?
Aegislash and Zapdos are the only Pokemon that those two together can't defeat if Lucario goes for Iron Tail, and Clefable, Sylveon, and Zapdos if Lucario goes for Earthquake. However, this is assuming said Pokemon switch into either Latias or Lucario, as in 1 on 1 situations, there are much more Pokemon that can beat this core, such as Azumarill, CB Talonflame, Choice Scarf Excadrill, DD Mega Gyarados, Gengar (if it wins the Speed tie), Greninja, Latias, Latios (again, Speed tie), physically defensive Mega Scizor with Superpower, Mega Mawile, and Mega Gardevoir. Lastly, there are some Pokemon that can threaten one of those two Pokemon while the other Pokemon is unable to switch into them or check them after they set up, such as Bisharp (threatens Latias), Mega Charizard X (threatens Lucario), Mega Pinsir (threatens Lucario), and Mega Tyranitar (threatens Latias).
The best thing that the CAP can do to cover those weaknesses is to be able to defeat most of those Pokemon 1 on 1 at worst, or be able to check most of them at best. The best way to do this is obviously with the right typing and bulk. For example, some of those Pokemon can beat our two Pokemon core with just a single move (CB Talonflame with Brave Bird, Mega Mawile and Azumarill with Play Rough, Mega Gardevoir and Sylveon with Hyper Voice, and Choice Scarf Excadrill with Earthquake), so having a Pokemon able to switch into those attacks will at least make all those threats think twice before spamming them. So, resistances to Fairy and Flying moves are musts, as those attacks are so powerful that can't be handled otherwise. Also, the CAP should definitely be able to check Aegislash in one way or another, and there are only two ways we could go about doing this: good special bulk with neutrality to its most common moves, or Bulletproof and neutrality to its most common moves. Going with a Dark or Normal typing to resist Shadow Ball is not an option, as then the CAP would be unable to resist both Flying- and Fairy-type moves, something which is necessary. We could maybe go with a Normal / Fire, Normal / Poison, or Normal / Steel typing, which resists or is immune to Ghost and Fairy, but the CAP should then have physical bulk to the levels of Landorus-T and Hippowdon to be able to take CB Brave Birds from Talonflame.
4. What role should CAP 18 have in this core?
Given that our two Pokemon so far are very offensive in nature, the CAP should follow this trend. It should be able to check or at least beat 1 on 1 most of the Pokemon that trouble Latias and Lucario, while being able to threaten a big variety of Pokemon in general, so that each member of the core isn't easy to wall separately (something that Latias is already guilty of). Ideally, the CAP should be able to handle the Pokemon that threaten Latias and Lucario and take advantage of them, in order to lure or weaken some Pokemon that get in the way of Lucario and Latias, opening the way for them, and vice-versa. This means that it would be a desirable thing for the CAP and Lucario / Latias to have some similar checks and counters, as long as the CAP can damage those checks / counters enough for the other two to get past them.
A good example of an offensive partnership i would like to see from Lucario + CAP is CB Talonflame + CB Staraptor. Both Pokemon have similar checks and counters that can be worn down, such as Landorus-T, Hippowdon, and Slowbro, and both Pokemon can deal with Pokemon that trouble their partner, with Talonflame being able to deal with Skarmory, a hard counter to Staraptor, and Staraptor being able to handle Rotom-W and Heatran, two hard counters to Talonflame. Of course, we would have to take it one step further, because as you can see neither of those two Pokemon (Talonflame and Staraptor) can switch into the Pokemon that wall or check the other (Staraptor can't switch into Heatran or Rotom-W), they can just beat them 1 on 1.
A concern that has been presented here about Latias is that she is easy to trap with Pursuit users such as Tyranitar, Aegislash, and Bisharp. Lucario can already take advantage of Tyranitar and Bisharp in order to set up, so it would be nice if the CAP would be able to set up without much fear in the face of Aegislash, to make sure that no matter which Pursuit user the opponent employs, it's going to get punished for it.
5. How are we going to make sure this Pokemon benefits Lucario and Latias more than any other Pokemon, especially Pokemon that perform similar roles as Lucario and Latias?
Latias is a great Pokemon in OU and faces competition mainly with Latios. However, she has her distinct advantages, which are better bulk and Healing Wish, so as far as we take advantage of those two, our core will be fine. Yeah Latios may replace Latias in the core sometimes, but he won't in any way overshadow her, as we know from the OU metagame, where both Pokemon are very viable choices even though they compete for the same slot.
As for Lucario, it may face competition with Mega Pinsir and other physical attackers with priority, but it also has very distinct advantages and a big niche as a sweeper.
Lucario is one of the few sweepers that doesn't have to worry about Talonflame, Thunder Wave Thundurus, and Choice Band Dragonite's Extremspeed, which is in itself a very important advantage over other physical sweepers, as those Pokemon are some of the best ways to keep in check the multiple sweepers found in OU. Also, the combination of defensive Pokemon it beats is unique, as unlike Mega Pinsir, it can beat Skarmory and Rotom-W, and unlike SD Bisharp, it can beat Mega Scizor, SpD Mega Charizard X, and Skarmory. Finally, if we truly design the CAP to have similar checks and counters to Lucario, while also beating some of the Pokemon that trouble Lucario, this would mean that the CAP performs better when used with Lucario and not other sweepers, which would be one more reason to use Lucario with it.

He is one of the few pokemon to possess powerful STAB on both sides of the spectrum (Close Combat/Iron Head for physical, Aura Sphere/Flash Cannon for special)
Lucario doesn't get Iron Head.
