The only real hope I can see is that there's been something of the same rebellion that saved Dick when Didio was going to kill him; enough writers, or enough prominent writers, have complained to Levitz about curing Babs and spinning her back to Batgirl that Levitz said no.
I'm not *hugely* optimistic this has happened, but I know that at least in the past, DC people have objected to fixing her spine on the grounds that she was a rolemodel to a lot of handicapped readers.
I admit, I'm conflicted on her being cured; in one sense I don't like that male characters get fixed but females stay damaged, especially since it's a memorial of such a shitty misogynistic plot. But it has allowed her to develop as a character, and has protected her from the kind of character development erasing that happens so often. Writers can't just get on a book and instantly turn her into the catsuited ass-shaking "girl" that they masturbated to so fondly when they were kids.
