I'd like all of the Robins to be incorporated as their own personas, like Nightwing was in this one. . . With their own story mode, of course.
Nightwing, Red Robin, Red Hood (I'd like this one. Imagine being someone who uses guns in a Batman game!), Damian Wayne...
The batgirls too could show up. Even Barbara Gordon, seeing as the newest continuity reboot gave her back the use of her legs.
