Haven't updated this in a bit. We have been mostly concentrating on James 2WD car. The 4WD is under a major renovation. Most of the major architecture has been laid out to move forward, we need to pick and mount batteries and finalize the steering servo mount in order to continue moving forward. Realistically, with the weather we have here in NJ it's likely going to make its first test hits in spring with a goal of 75mph on 6S.
I did end up replacing the blown capacitor with some help from my brother who is a robotic engineer and is generally much more knowledgeable about how electronics works and how to service them (my background is all electrical). Long story short, the exact replacements for these were 2 months away in China so we found a Panasonic capacitor of the same capacitance, voltage, and diameter. It's a little longer. Very, very carefully removed the epoxy that holds it in, broke the old one free from the board, soldered in a new one, and poured new epoxy. I had to dremel away part of the outer housing to get enough room to get even my smallest pencil tip in on my Hakko.
I don't have a vehicle currently capable of throwing this and the motor in to see if it works. I bench tested it with a motor, and it seems fine via the DVOM. I really didn't notice any problems running on 2/3 capacitors, they are really there to just stabilize the voltage going into the board it doesn't "boost" performance in any way.
