It's definitely something CBS can fall back on if the initial idea doesn't work. Bringing back as many past cast or spin-off characters is what this series needs to not be unique.I'm the opposite. While I hope that the show can stand on its own with a new cast, I do want to see what's become of the old crew. I also wouldn't mind seeing Wesley and a few guests from the other shows. Janeway is someone else I expect to see. It could be argued that the show would feel too crowded with throwbacks to the old days but they were his crewmates and friends, so it could work.
