To be honest, even with the stuff suggested I think he'd work a [i]lot[/i] better as a villain than a member of the crew, but that's just me I guess.

I'm fine with that, though it'll be hard to make him more than a single arc villain. I can't think of a single villain who was serious that lasted more than 1 arc. Buggy isn't serious so he doens't count.
