I don't think we need to have a reunion of the Voyager crew in a movie about Picard that's already going to try and do some TNG reunion stuff. Using Seven is good enough. I mean, maybe "at most" we could reunite with some DS9 character to just get the "trifecta" of the TNG-era casts. Though I'm not sure who you would use, maybe Jake could've been the hostile FNN reporter.
But, then, that'd make him look bad.
