Barbara will stay Oracle anyway. She can coordinate.
Ok, fine. If Cassandra isn't going to be Batgirl, I want a TEAM of Batgirls. You heard me. Steph, Cass, Charlie...hell, go get Sin from wherever Green Arrow stuck her. Swarms of Batgirls taking care of Gotham while Dick keeps Damian from doing anything bad and Alfred runs the Outsiders and Tim goes and broods in foreign countries. We can even give the costume back to Helena, not that I'd think she'd want it anymore.

In face, why hasn't this been done with any heroes before? It would be brilliant for maintaining a secret identity, especially for the non-powered Batcrew. Even better, the Batcrew has worked on maintaining an air of mystique about themselves that lends itself to multiple behind-the-cowl characters. I mean, there's been a couple of Batmans, and as far as we know, the average Gothamite is none the wiser.

And, yes, there are two Green Arrows and lots of Green Lanterns, but they each maintain their distinctiveness on purpose. I'm arguing that the Batgirls should claim (at least publicly) to all be the same person.

If they're going to change my favorite status quo, this could actually be pretty cool.

(I could also totally see Steph getting into the DAAARK VEEENGEEENCE shtick with Charlie. Cass would still be silent and deadly. I would also like it if they retconned out every mention of Evil!Cass ever, while we're living in my fantasy world.)

(I also don't know if this idea is entirely a product of my brain, as it has been mentioned a few time on scans_daily and I honestly can't remember what came first. So disclaimer!)

EDIT: Apparently it was kingrockwell of InsaneJournal who mentioned it first on Scans_Daily. As that was probably how the idea started seeding in my brain, I'm giving credit.
