Riddler or Penguin because anyone with super powers would feel weird in the Nolanverse. Though Bane could make sense if they limited just how much Venom can pump a person up to a reasonable level.
I can only think of 1 mainstream batman villain that has what I would consider "super powers", and that's poison ivy. she has powers that are clearly above and beyond the scope of a normal person. She has pheremones, poisonous kiss, and the ability to communicate with plants.
Who else has "super powers"? Bane? Ehhh, alright, I'll give you bane I guess. But steroids actually do exist, and when you look at some professional baseball players, or wrestlers, you can almost see a Bane type character in real life. Like you said, limit the actual size and the strength to "just above human", and you have a toned down and viable villain.
Dr Freeze himself doesn't have super powers. In fact, if anything, Dr Freeze has a weakness but no inherent powers (other then living in freezing temperatures comfortably), but there are human beings in real life that have a similar ability. His offensive capabilities (and even his ability to exist in a world where he can harm anyone at all in most incarnations) is determined by technology, rather then his own "super powers". Limit his technology to "close to real", and suddenly he's not super powered.
I think Dr Freeze would be pretty awesome. Could you imagine his origin scenes? Some sort of freak scientific accident, and suddenly he is getting first and second degree burns just being in room temperature? I think that would be cool.
Two-Face, as I've mentioned before, definitely straddles and the far side of reality, and Scarecrow, while not "super powered", definitely had abilities, granted him by his scientific knowhow that put him above a common man, much like how I described Dr Freeze.
I think Nolan was caught in a bad place with that quote that we're referencing, and was basically saying he didn't want his batman legacy to become Campy. That he was staunchly against his movies paying strong tribute to the 60s sitcom. And I think that's something we can all agree to.
