Good questions!
There was a forum member @
neutron256 that went really far into trying to build an open-source ESC. A dedicated, capable, and very smart guy he worked for over a year on this project (the thread lasted 15 months). He ruled out Supercaps/Ultracaps but wasn't specific as to why (read here
http://www.ft86club.com/forums/showp...&postcount=170 ). His thread should be required reading for ESC enthusiats as it really illustrates just how complicated putting together a functional, reliable, and powerful ESC really is.

Ultimately there's a difference between what's possible and what's been tested and approved by Rob. Anyone is free to test whatever battery setup they like at their own risk. I think Shiv tested this behemoth (or something like it a lil while back)
Yes, that's a $1300 battery.
http://www.lithiumion-batteries.com/...on-battery.php Problem is, adding $1300 to $1800 kit price and the Phantom loses its' cost/performance advantage to a home installed turbo at 10 psi. This is the game.
Since were talking hypotheticals @ cost no option, why stop at 24 volts, how about 36?
For the low-low price of $4100 and possibly a cooked controller, you can plug this beast in.
http://www.lithiumion-batteries.com/...attery-kit.php . Ok so then let's just upgrade the controller and recharge mechanisms. How much are we at now? Answer: Lots.
Fun!
Really though, Rob is years ahead of anyone in the aftermarket on this because of his engineering, machining, and motorsports experience that drive his component selection, custom component fabrication, motor controls, and design decisions. Add a small army of users providing feedback to the years of R&D he's put in and wow. So then there's Shiv's input that even further widened the gap in the aftermarket. This is not to say that the kit can't/shouldn't be improved, but that many of the ideas I've come across since getting into this back in 2013 he has already vetted. Yes, the documentation needs regular updates, and this forum has done well to help keep things together. I'm no fanboy, but when looking at years of someone doing their best in their field of expertise it's hard not to be impressed.
