I think that RPDR could actually do an all star Hero vs. Villain as AS 4 (or i guess 5 since 4 is filming soon). It could be run the same way as the first two eps of Season 6 where there's 10 queens, when it comes to f6 (3 hero, 3 villain) they "merge" and maybe one comes back.
Heroes:
1. Cracker
2. Monique
3. Ongina
4. Shea
5. Valentina (even though she should be a villain)
