In the meantime, if I were to run a DFAE game, I would probably keep it as is for the most part, maybe replace flashy with something akin to faith, as that's a big part of the world. Unfortunately, I can't seem to think of a good name right now.
Magic would just work with the approaches as they are. Want to throw a fireball at a ghoul? That's a forceful attack. Most other powers would be rolled into aspects, the parts of powers that are supposed to define a character will be stunts.
