Theorycrafting - Turn FF6 into FF4?

All in all though, the big question I'd ask of this is "why"? There's nothing you'd gain from this that you couldn't get by hacking FFIV.

Admittedly - I know. The major thought that spurred this was that it seems FF4 hacking is not as in-depth as FF6. At the least I haven't seen any FF4 editing tools that offer a full breadth of data viewing and editing similar to FF6usME. But of course, the amount of work that would need to go into such a project would be better spent just learning how to hack FF4 better. And replaying it on its own just as a player would probably not be a big deal.
