I mean, think about it. Arsenal, Kid Flash & Miss Martian were originally part of the original 7. Also, since there is a Superman (& Supergirl), there's a chance there could be a Superboy later, too. Miss Martian was Beast Boy's stepsister (not to mention he made him who he is) in Young Justice, so I really think he should be in it, too. One more thing, Cyborg Superman resembled Victor Stone (but it was coincidental, understandably), so Victor Stone's incartnation can't be too far away either. & about Robin, Batman & Green Arrow used to have a friendly rivalry in Batman: the Brave & the Bold, & Batman & Superman also had notable rivalries, like in Batman vs Superman: Dawn of Justice, Lego Batman 2: DC Superheroes, Lego Batman 3: Beyond Gotham & The Dark Knight Returns. With that being said, Batman has to be in CW, so I think it's a given that Robin should be in it, too. &, Not to mention, Starfire's superpowers are very similar to Supergirl in terms of Flight eye-lasers, & super-strength. So she should be in it, too. That just leaves Raven...
