re: What Batman Villiains Would You Like To See In the Future?

Mr. Zsasz. Have the whole parallels with Wayne.

I'd say Killer Croc or Clayface, but I'm unsure how they'd be made "real". You could probably take on the wrestling part of Croc's background, but sets it up as just a ground and pound villain. Clayface could be a master of disquise, without crossing too much into Hush territory.

ETA: But the above point about portraying Zsasz in a certain rating standard makes it a bit more difficult.
