A Different Sort of Kefka Hack

Well, mostly the thing that's keeping me from just doing everything myself, is the fact that most rom hacking software doesn't work for Macs. Now, is there simple, easy to use FF6 hacking software that works for Macs? Do any of the Windows hacking programs work through Wine? Getting another computer is not an option for me, money-wise. I'm stuck with a Mac.
If someone tells me, "Hey, just give me the script and graphics, and I'll jam into the game for ya!" I'd be willing to commit myself to this work. Otherwise, I feel I'm better off returning to my professional work.
Honestly, I did NOT put much thought into this idea AT ALL. It came to me this morning on a whim.
