Actually Oliver would be amazing. They said Oliver was dead but that could have been fake, they don't need Amell for every episode, they could just keep zooms mask on, and in the grave scene, Oliver referred to him as "zoom", when it's most likely that Barry knows his identity by then. He could just not have told him, Oliver being zoom would make arrowverse the ultimate single show.
