So, late to this party but here's what I would like to see happen. Star Trek: Legacy with Captain Seven on the Enterprise G can get corrupted or co-opted or lost in time. It's not beyond them being used by the Temporal Investigations division. Since in the past Star Trek has largely used time travel to completely change a given timeline leaving no Trace of that which came before, perhaps Seven's mission is to clean the timeline. They can travel back and forth to different eras. We can see different crews and events. They can be the unity between disparate timelines and time periods.
