I agree, the PC version possibly...
Well, to my knowledge talking about rom images and emulators is okay here on LF provided you have the legal requirements to possess a rom image (the game that the rom is actually OF). It might not be all that different from modding a PC version.
If you managed to get a proper emulator with a rom image (I'm assuming you HAVE the game so this is all legal) and a bit of programs...decompliers/compilers, script tools, resource editor stuff, graphics programs, etc., then I suppose you could remodel TPM.
It's an icky process, but I think it would achieve more or less what you'd want it to do.
Just my 2 cents.
