To be general purpose you need to find a game that would be most problematic, if it can't handle the worst case then it's not worth doing.

To be able to do what you're trying to do then you should be able to do that yourself much quicker than asking questions to someone who is probably in another time zone.

The DRC runs all the code, it never drops back to an interpreter.

As long as your approach works off the original roms, can start running the game as quickly as mame already does and still achieves a 25 times speed increase then yes that would be interesting.
You can't legally distribute a machine translation of a copyright file, so you have to be able to work off the original roms (because a real user can dump their own roms). You'll need to rebuild your translated code when a bug is fixed in the translator.
You need to be able to cope with indirect jumps. Jump tables or pointers might be calculated at run time, so they might not be available when you need them. Even if the jump table is available, you might not be able to work out what size they are.
static recompilation is very useful for porting games from one platform to another, you can special case bits by hand to make it work & even change the resulting source code before compiling it. MAME has to be able to cope with running any software, if you write software for galaxian hardware then it should run in MAME by just naming the roms correctly.
