Jason Todd is a fucking psycho. If he's Batman, he's not going to be part of any team, or any alliance. He's going to be the Punisher in a bat suit. The likeliest scenarion has there being two Batmans after IC. Jason Todd and Tim Drake. Tim is the "approved" Batman, while Jason just decided to appoint himself Batman one day and goes around killing everyone in sight. This could be pretty cool.
