I flipped to the back of this, saw Babs was still in a wheelchair, said "YES!" and put it back.
I think if Babs was to suddenly become Batgirl because of the crystals in BG #1, they'd have someone other than a guy who wrote a few Smallville episodes writing her return to the cowl. There's gotta be someone in DC who'd be all over that. So I'm cautiously optimistic we won't see Babsgirl. I think your theory, that they were going to but thought better, is correct.
