So I recently bought the first two golden age omnibus's and I love them. I like the first few stories featuring Doctor Death and Mad Monk. I really think it would be cool to see classic villains like them return in the mainstream continuity and for over used villains like Joker, Riddler, and Penguin to take a back seat for a while. I say this because I think it would be interesting to see Doctor Death return as a serious threat to Batman as well as Mad Monk to return to. I'd also like the Spook (who wasn't in the Golden age but still a good classic I think) to return as well. I think there are a lot of classic and or forgotten villains that deserve a time to shine and I think it would be nice for DC to do this rather than just invent new enemies for Batman.
