Final Fantasy VI SNES Woolsey Uncensored Edition

So I'm going through the weapon names and decided the GBA names work really well. There are some item names I'm running into that the character limit is just....grrr!

If I were to mess around with Angelo26's patch, it would increase the ROM size and I'd have to learn where the new names are and how to edit them. Question I have is, would it work on actual hardware, bsnes, etc if I were to implement his patch? It would solve my class names thing.
