While for many it's unthinkable to even ponder anyone else but Ledger as The Joker (especially given all the awards the actor has posthumously received), the site points out that producer Charles Roven recently suggested to MTV that the role is more important than the actor playing it.

So might the Joker be recast? Or, if it's just a small role, could Ledger's Clown Prince be digitally recreated a la Oliver Reed in Gladiator or Brandon Lee in The Crow in order to have the character make an appearance? Given today's special effects, that's certainly possible. But, as Moviehole stresses, right now the studio and filmmakers are simply tossing around ideas for a third Bat-film so this is all just RUMOR
