I can only say that if you think you can do it, then I think you can do it.
It certainly would be cool.

Noting that SuperROM has never been found (or never released?) for
NEC, it seems to me given what I know about making applications run on
both platforms, that it should be very straightforward to translate
the M100 SuperROM into an NEC variant. After all, the NEC and M100
are so similar.
Does anyone have any thoughts on this?
Process could be:
- Disassemble
- find the trampoline, and adjust for NEC memory map
- look for "trampoline" calls to the main ROM, and convert to NEC
addresses
- look for upper RAM addresses, and convert to NEC addresses
---> this could be a bit tricky I admit, because it may not always be
apparent that a register pair value is being used as an upper RAM pointer
- adjust the hardware interrupt if needed
