Batman: Bruce
Robin: Damian (as much as I hate the little sh*t, long term he has more potential)
Batgirl: Cass (see above without the hate part)
Let Dick be Nightwing, or Grayson, and let him be separate; the Robin who flew the nest and adopted his own stage, became his own one-man show. Babs became more effective as Oracle than she ever did as Batgirl, and taking up that role doesn't mean she has to sit in a wheelchair again. Jason to me is always going to be that tattered costume in a glass showcase. As Red Hood, he only works as the corrupted one, the Robin who fell from grace into infamy; let Dick be the heroic outsider, not Jason. Tim's position has been usurped by Damian, frankly I'm surprised he even still exists; if I had my way he wouldn't, at least not as a Robin. Steph... let Stephanie be the Spoiler, the wannabe, the not-quite-good-enough-but-still-tries-her-hardest third-party observer to the whole Bat-family dynamic.
And let Bruce be sexy! Snyder said something not too long ago about how the women ogle Grayson and his unmistakable tush and he goes, "hey look over here! Bruce can be sexy too!" and the women don't see it, only now they do because he's got the sexy beard and jeans. I think there's something to that; I thik that to a certain extent Bruce, through broad portrayal and in contrast to other characters, has gotten this rep as an asexual, unapproachable, monolithic engine of justice. And that's not sexy, it's not approachable, it's not relateable, it's not human, and that's the real shame because Batman is human, Bruce is human.
