The only other known female I can think of is Krawl - Hostile Women. I would say she could be Edna but Edna was never really all that hostile. Patty and Selma were very hostile so she could always make the cut for one of them. Maybe Jinx's sister can be the other. Idk, Just suggestions. Also, if your trying to fill up the spots, seeing as Void lost his spot as Mr. Burns, you could make him sideshow Bob.
