Don't think we could introduce the whole Green Lantern lore without a show on them itself. Also we already got Hawkman and Hawkgirl. They were on Legends. However i hope we see more of Earth-X Red Tornado. Who was pretty cool in Freedom Fighters and the crossover. Batwoman would be cool to have on the show. Would have worked better while Maggie was still on it though. Mister Bones would be a cool member too. However if anyone was going to be on Supergirl, i wouldn't just put in random supers like Starfire, i would have someone associated with Kara such as Brainiac.
