That could happen pretty much no matter what barring a system change. Of course, if I'm throwing one at you, I'd probably want at least half a dozen trials. You know, so the results are statistically significant.
I'm not sure what the second and third sentences mean here in context of the first.
Hmm... what kinds of systems have you considered? Off the top of my head...
Pathfinder is the closest to D&D, and close enough that homebrew can be ported over with little problem. It's also a can of worms of the raeg kind, of course.
DFRPG can be used for Eberron pretty much straight (and it's one of the ideas I've been tossing around myself), albeit at a more down-to-earth feel (and power level) than the original campaign.
Exalted would be pretty much the feel and power level of the old campaign.
Come to think of it, Lucy and Kuroi's character would pretty much be Abyssals right out of the box. And there
are charms for killing shit with music.
Other weird shit: I'm sure someone has made an indie game involving the power of metal out there. I just haven't found it yet. M&M works for anything. Magical Burst and MAID are just fun.
