There is no reason for CC to work faster on MMM version. And it is very easy to build prototype unit in R&D but it will takes tons of time before it can be released to public.

Can MM be upgraded - sure why not, can it be done within the same package - questionable, can it be done cheap - possible.

Here couple thoughts:
For MM to handle higher voltages you need to modify software as well, that's a little bit more tricky then just swapping fets or adding couple daughter boards. But we can always set it to custom voltage, right (thanks to flexible software).

Do you need high current at higher voltage - good question.
What is more important that with higher current (or the same 100A) and higher voltage (4S+) capacitors are growing in size, so current package is doomed, unless we increase price and let electrolytic caps go home :)

Well, bottom line if you want to upgrade one, send it to me I will take a look and maybe do something about. In the past I've done lots of upgrades to ESC from any brand and flavor.
