It's not crazy, it's just unconventional. If you could fit one and it had higher output than the stator, it would be great.
Just gotta figure out how to drive the alternator. One thing that comes to mind is friction drive. Have a pulley contact the rear tire (rubber to rubber) with enough tension and it should be able to drive it. Basically like bicycle dynamo, but using an alternator. However, I dunno if this would affect the tire in a negative way.
I read that that's how they drive those hubless wheels, by using some kinda rubber pulley or roll or some kinda rotating thingy that contacts the rear tire with enough force to drive it. Not sure if it's that simple or not, but for an alternator it shouldn't be more complicated than that.
