Would have been cute to see what happens with Seven and Chakotay, eventually noticing that the Doctor was determined to win Seven's heart in the first place.
There would have been purrtential for this movie though! Dominion coming back, Borg trying to build a new transwarp hub in the Alpha Quadrant, Voyager assisting Starfleet to convince the Dominion to fight together against a bigger enemeow. ^^
(That was cat language.)
