Honestly, I'm not too keen on the idea of more classic rehashes. WW, Harley, Ivy and I presume CW are justified in that they serve as replacements for the four produced in that brief awkward stage between the first and third sets.
I'm content with the AH girls, so if there are going to be repeats, I'd like them to continue with the nu52 designs.. Or at the very least, alternate designs that set themselves apart from the original, classic interpretations of the characters. Although I'm sure a select few out there would brand me a heretic for even suggesting it.
Zatanna and Black Canary are two I'd likely get regardless, but I wouldn't mind seeing something fresh.
Aside from that, put me down for Wonder Girl/Cassie Sandsmark, Stephanie Brown and Cassandra Cain.
Would have said Donna Troy, but I'd have liked her in the AH! line to display alongside Starfire and Raven.
