1. What should the build of our Pokemon be? (eg. Bulky offensive, hyper defensive, etc)

My preference for this is actually closer to the Rhyperior model I alluded to earlier, where the Pokemon combines a specific offensive and defensive strength with some other weakness or set of weaknesses that set it apart. A good OU example I think would be Magnezone, which has an incredible niche for itself as well as an inherently dangerous offense and serviceable defense.

2. What facet of strategy should this Pokemon's focus be on? (eg. Support, hyper offence, etc)

I think a hybrid of set-up sweeper and support would provide the best elements of risk, since the two strategies would be mutually exclusive on the same set but would be able to test not only the effects of high risk, but the value of a set dedicated to reducing it. I'm thinking a combination of setup sweeper with dual screens capacity, kind of like Metagross if it had a more offensively oriented typing.

3. In which parts of the process should we focus on Reward, and in which should we focus on Risk? (eg. Low Speed so reliance on set-up moves, etc)

I'm going to borrow the breakdown from some other users.

Base Stats: Obviously these are important. Based on my own posts I feel like having a dedicated 130+ Offensive Stat and some combination of a single useful defense would be the best way to go.

Typing: Here I would actually try to avoid things like 4x weaknesses and instead go for a suite that mixes common and uncommon 2x weaknesses with a decent offensive typing. Electric/Psychic would be an example of this risk level of typing where it combines a U-turn, Pursuit, and an Earthquake weakness with a STAB combination that lends itself well to taking common priority attacks like Mach Punch and Bullet Punch while resisting Tornadus-T's Focus Blast/Hurricane combination.

Ability: Ability is integral in risk management and I would prefer one that interacts with the Pokemon's diverging movesets differently. Analytic immediately comes to mind as it increases the risk of a slower dual Screen type set while it becomes somewhat of a liability on a speed-boosting set, except when opponents are switching or using priority.

Movepool: A Decent support and setup movepool are the ways I would want to go in managing risk so as to get a bigger picture of what is needed. With the proper STAB attacks I don't think CAP4 would need to focus as much on coverage and just stick to brute force execution.
