Writing and recording is so far ahead of animation, I can't see that happening. Plus there's the Stagg appearance which was a clear not to Metamorpho turning up.

If Hardware and Batwoman were there and Plas was the only one from 301 missing, then that'd be weird, but as it is it's just two characters with overlapping power sets, which is hardly unusual for YJ. And Orphan showed they're quite happy to debut new characters in these new Outsider teams.
