The thing about Two-Face for me, I don't think his dual sides can really be achieved in the tone this series is going for. He's fun for having bank robberies where he only takes two dollar bills or whatever, but the only way you can make him both a "good" and "bad" villain is having him bump off corrupt cops or politicians, which is a mix of what Nolan did and what Riddler is doing in this film, or having him going after criminals he knows are guilty but can't legally touch, which again is a mix of Nolan and this film's version of The Riddler. In a more lighthearted or heightened tone for Batman you can have his "good" side becoming conflicted in the middle of a bank robbery and taking over, but for something like this I don't think you can do that without being cheesy.
