Well you covered capacitors and BEC very well, couple things to add FET's ratings and FET's control logic capability to drive high side of the bridge. ESC rated at 6-7 cells not designed to run more then that without commutating problems. Then we have ESC with good and cheap FET drivers. Good automatically adjusts to required voltage, only caps and FET are the limits. And cheap with fixed voltage which is good only up to given maximum number of cells.
And do not forget about electrical noise, higher voltage requires better suppression.
So you can try, but keep that in mind.
