Naw. She's only been around a few years and couldn't carry a movie. Come to think of it, Batman does has a pretty thin rogue's gallery of real world types. That is, non 'super' types.

I think Riddler could be interesting as would the Penguin. After that though, I'm a little stumped. Deadshot, maybe? Or maybe the original Clayface reworked? He was originally a serial killer. If they add disfigurement, disguise, hacking, and general identity theft he could be an interesting supporting villan.

Maybe reintroduce a revised Catwoman?
