Maybe a different spin off League with Wonder Woman, Zatanna, Aquaman, Martian Manhunter, Flash (Wally West), Raven, Shazam, Blue Devil and Detective Chimp specializing in dealing with magical threats. Call it 'Justice League Magic' or 'Justice League Arcane'.
Also, do a solo series; a YA style retelling of 'Zatanna's Search', the story arc with her mother and culminates in her adopting a look that fits her best.
