Interesting plot theory for season 4. Although, I wish they could use the Supergirl: Red Daughter of Krypton storyline from the comics for season 4. In the comic story, Supergirl becomes a Red Lantern due to all the turmoil she gone through from from feeling more alone and alienated than before and that all her relationships (whether is love, family or friends) didn't turn up so well. Season 4 could be the introduction of the Red Lanterns and, possibly, the Green Lanterns in Earth-38.

Also, for season 4, I wish we could see the introduction of J'onn J'onzz's evil twin brother, Ma'alefa'ak.
