I know, edge if not wishlisting, BUT I know there are probably some people who are wondering what other kinds of Poke Balls they could make (that aren't obvious ones based on a Pokemon's Type) so here is a quick list of ideas I had written down somewhere:
Red Apricon Plus:
Blue = Climate Ball (3.5x on Pokemon who are positively affected by active Weather)
Yellow = Thermo Ball (3.5x on Fire- & Ice-type Pokemon)
Green = Ailment Ball (3x if Pokemon is afflicted by poison, burn, confusion, binding moves, curse, leech seed, nightmare, & Perish Song)
Pink = Tally Ball (Starts 1x, for each Poke Ball the Pokemon has broken out of the Tally Ball's Catch Rate increases by +.5x, maxing out at 5x)
Black = Exhaust Ball (If the Wild Pokemon breaks out of it than it's HP is decreased by half; Wild Pokemon's HP can't go below 1)
White = Drain Ball (Starts 1x, for every 10% more HP your Pokemon has to the wild Pokemon the Drain Ball's Catch Rate increases by +.5x, maxing out at 5x. If the Pokemon breaks out than 10% of the Wild Pokemon's HP is drained and given to your active Pokemon; Drain still happens even if your Pokemon is at full HP & Wild Pokemon's HP can't go below 1)
Blue Apricorn Plus:
Yellow = Lock Ball (2x Catch Rate. Only does 2 Shake Checks instead of 3 if not a Critical Capture)
Green = Earth Ball (3.5x on Ground-, Rock-, & Steel-type Pokemon and Pokemon in the Mineral Egg Group)
Pink = Rarity Ball (If Pokemon's Catch Rate is 101 or below the Rarity Ball's Catch Rate (modifier) is 1x, between 100-51 is 2x, between 50-26 is 3.5x, between 25-11 is 5x, and 10 or below is 7x)
Black = Diffuse Ball (4x on Pokemon that learns a self-knock out move (Explosion, Self-Destruct, Final Gambit, Healing Wish, Lunar Dance, Memento, etc.), 8x if it knows the move. If you caught a Pokemon in the Diffuse Ball and you had it use a self-knock out move during a battle, at the end of a battle if its still fainted it'll be revived with 1 HP)
White = Gravity Ball (3.5x on Flying-type Pokemon and Pokemon with the Levitate Ability)
Yellow Apricorn Plus:
Green = Nature Ball (3.5x on Grass-type Pokemon and Pokemon in the Grass Egg Group)
Pink = Sun Ball (4x on Pokemon who evolve with Sun Stone, evolves with Shiny Stone, evolve during the day, only come out during the day, know or naturally learn Sunny Day and/or Morning Sun, have an Ability that interacts with Sunny Day (Drought, Solar Power, Flower Gift, etc.), or are sun-related (Solrock, Larvesta family, Solgaleo))
Black = Height Ball (If Pokemon's Height is 1 meter or under the Height Ball's Catch Rate is 1x, between 1.1m-1.2m is 2x, between 1.3m-1.4m is 3x, between 1.5m-1.6m is 4x, between 1.7m-1.8m is 5x, between 1.9m-2m is 6x, between 2.1m-2.2m is 7x, and 2.3m & above is 8x)
White = Pester Ball (2x Catch Rate. If the Pokemon breaks free they Flinch)
Green Apricorn Plus:
Pink = Growth Ball (Doubles increases to EVs & Experience (and Contest Condition, Performance stats, etc. if they're in the game). If healed or has PP restored by a certain amount doubles that amount)
Black = Dread Ball (3.5x on Dark-, Ghost-, and Poison-types)
White = Egg Ball (3x on Pokemon which can be hatched from an Egg)
Pink Apricron Plus:
Black = Form Ball (3.5x on Pokemon in the Amorphous & Ditto Egg Groups)
White = Fable Ball (3.5x on Dragon- & Fairy-type Pokemon and Pokemon in the Dragon & Fairy Egg Groups)
Black Apricorn Plus:
White = Plain Ball (3.5x on Normal-type Pokemon and Pokemon part of the Human-Like Egg Group)
Also if you combine two Apricorns together you get two of the Apricorn Balls the combination makes instead of one.
Also I think they could also fix up some effects of the existing Apricorn Poke Balls:
Level Ball (If your Pokemon's level is above the wild Pokemon's level the Catch Rate is 2x plus 0.1 for each additional level higher. A Pokemon caught in a Level Ball doubles Experience gained if Pokemon isn't highest Level in your party)
Moon Ball (4x on Pokemon who evolve with Moon Stone or Dusk Stone, evolve at night, can naturally learn Moonlight or Moonblast, only come out at night, or are moon-related (Cubone, Umbreon, Lunatone, Cresselia, Darkrai, Lunala))
Friend Ball (A Pokemon caught in a Friend Ball has their Friendship (and Affection if in the game) set to the max and prevents it from being lowered. Doubles the chance of a Affection Benefit of happening)
Love Ball (3x on Pokemon of the opposite gender of your's, 5x on Pokemon of the opposite gender and same Egg Group of your's, 8x on Pokemon of the opposite gender & same species family or species relation* of your's. In wild battles, will Infatuate opposite gender opponents when sent out)
* Species Relations: Nidoran family; Tauros & Miltank; Volbeat & Illumise; Latios & Latias
Heavy Ball (If Pokemon's Weight is below 10 kg then Heavy Ball's Catch Rate is 1x, between 10kg-24.9 kg is 2x, between 25kg-49.9 kg is 3x, between 50kg-99.9 kg is 4x, between 100kg-199.9 kg is 5x, between 200kg-399.9 kg is 6x, between 400-799.9 kg is 7x, and 800 kg or above is 8x)
Fast Ball (If Pokemon's base Speed stat is below 60 then Fast Ball's Catch Rate is 1x, between 60-70 is 2x, between 71-90 is 3x, between 91-120 is 4x, and 121 & above is 5x)
(If you're wondering, I think Lure Ball's x4 on Pokemon fished up is good)
Of course, with all these new Apricorn Poke Balls it might be a bit overwhelming to remember which combination makes what. That's why I also think they should also introduce Apricorn mutations. Pretty much each Apricorn color has a mutation color that happens every so often (not common but also not rare):
Red's mutation is Brown, Blue's is Gray, Yellow's is Orange, Green's is Teal, Pink's is Purple, Black's is Rainbow, and White is Clear.
You can use the mutated Apricorn to make one of any of the Apricorn Poke Balls which requires that color. So for example, a Brown Apricorn can make either a Level Ball, Climate Ball, Thermo Ball, Ailment Ball, Tally Ball, Exhaust Ball, or Drain Ball of the player's choosing.
