What I'm working on now is the same footprint as the MMM -- but with 72 HV FETs (36 per side) and stackable. Would be good for about 130-150A in single layer, 225A or so in double layer using our newest FETs. (If we can drive that many of them without creating too many issues.)

Yeah, I didn't think it would be easy or small or even practical. It was a "wish list" after all, not an "
easy wish list".
TBH, the 200A+ and 20s capability is a tad overkill for most setups (maybe the 5th scales). But it sure would be neat to use an ESC like that in an e-bike or something.
And about "robbing" the parts, I was referring more to taking what already works and has been tried and true (like the MM brains) and experimenting with the power section. Just an idle thought. I know what it's like to have something you design be stolen, but it was not my bread-n-butter so it didn't matter so much.
