The easiest way is to merge them all under one title since the most popular name is TT but the most popular cast are in Titans, basically making it like the Young Justice TV with the older ones acting as a mentor
The selling cast would be Nightwing, Starfire, Beast Boy, Cyborg, and Raven with Donna, Wally, Wallace, Damian, Tim, Jason, Kon, Cassie, and Bart following.
