We have already in the comics or in episodes Riddler, Brainiac, Captain Cold, Lex Luthor, Black Manta and Gorilla Grodd.

I would like have Giganta/Cheetah for at least have some other than Devastation.

And Sinestro/Solomon Grundy because Sinestro is Green Lantern’s enemy and Solomon Grundy who is an enemy to Green Lantern´s Villain,  Batman´s Villain, Justice Society´s Villain, Green Arrow´s Villain,  Superman´s Villain and Justice League´s Villain.
