This doesn't strike me as the team Robinson wants...looks like some editorial mandates. Supergirl's probably out so her writer retains control--an ongoing is different from a mini. Bat-Dick seems like a "shove him in because JLA always has Batman".
Seems a bit random. I'd've preferred some continuity (of course, we're still waiting for the rest of Cry). Maybe the ones who worked with Hal become people he trusts enough to back him up? Because there's definitely gonna be leadership squabbles with Dick!Bat. That might be fun--bonus if the unknown archer is Arse Red Arrow.
