I don't know if we can have multiple characters outside of groups, but I suddenly have the urge to make a Wally West Flash who inherited the mantle after Barry dies in the Despero attack with the other Wally being Barry and Iris's son and the new Kid Flash. So Wally deals with losing his mentor after finally returning from the Speed Force and seeing so much that passed him by including a nephew named after him. He has to immediately step into his mentor's shoes and become the mentor he never expected himself to be.

Wally 2.0 deals with the loss of his father and having to live up to the legacies of both his dad and his namesake uncle.

I still want to continue to play as Seraph/Kieran and I know it took me a while to get my second post in, but I know I can manage all 3.
