What do u think about this supervillain for 'the dark knight' sequel?

in my opinion, i think that the supervillain in the sequel of 'the dark knight' should be 'hush' because he has a really cool background story that can be shown on screen such as that he was bruce wayne's childhood friend and his family was wealthy as well and also because he was never shown on screen in any batman movie til now......unlike the penguin, the riddler, mr. freeze, poison ivy and others who appeared in previous batman movies so.....i think 'hush' would be the perfect supervillain for 'the dark knight' sequel and maybe 'the riddler' can be the second supervillain in the movie because hush is the doctor of 'the riddler' and they work together against batman in the comics story so they can be together in one movie .....what do u ppl think?
