Stein already merged with that female Russian scientist but I get what you're saying. I don't know if they are capable of transfering between seasons but I could get behind Caitlin joining the Legends but I still stink it should be Dinah.

Roy would be good and I vote for Thea as well since they don't seem to know what to do with her in Arrow at the moment and she and Sara knew each other, plus it's be funny if the other Legends learned that Thea killed Sara.

Most of the examples you gave were just temporary though, the only real definitive one being Barry and Wally. Maybe Laurel can be an anti-hero to Team Arrow sometimes during seaosn 6 allowing Laurel and Dinahteam ups but I just don't see how they are both on the same team forever. Forgetting that many fans still aren't warming up to Dinah as they still see E1-Laurel as the true Black Canary and having E2-Laurel be around Dinah isn't gonna work long term because of it. One of them is gonna have to go by the end of season 6.
