Gordon-Levitt as Alberto Falcone?

I'm not sure about the validity of this one, but the rumour may be found below:

"It seems like Joseph Gordon-Levitt is the new go-to guy when looking for a villain. The rumor is that he may play gangster Alberto Falcone in The Dark Knight Rises. CBM has reported this from an anonymous source so we'll see if it holds up or not.

If Nolan is adding Falcone to The Dark Knight Rises, the character will fit right in seeing as the first two movies have involved the crime ring in Gotham. Alberto Falcone is the son of crime boss Carmine Falcone, played by Tom Wilkinson in Batman Begins. Falcone also has ties to Selena Kyle aka Catwoman and has played key roles in several of the Batman mini-series comics. So this kind of makes since doesn't it? Batman has gone in hiding, everybody is looking for him, good guys and bad guys alike.
So, what do y’all think if Gordon is actually cast in this role?"
