in principle, yes.
in practice, i'm not sure.
the key is box office. The TOS and TNG films built on both series being iconic and being pop-culture icons. Voyager never was. So this would be a setback in its marketing, or at the least its promotional aspects. i can imagine Paramount doing focus groups and other qualitative data, and asking people if they'd want a Voyager movie - "Janeway who? Delta what? Seven of who? What did you say the XO's name was again, the native American guy? Chuckles?" lol
It could be said that people would see a movie if it could be shown it had a good story and was well acted, or even by the marketing alone. I remember years ago the Blair Witch Project, the film was warped out, but people saw it because of the promotion of it. I guess the same could work for a Voyager movie. Even still, there wouldn't be the initial familiarity that other Trek films had . seeing a Kirk film, like the Undiscovered Country for instance, would bring in people who saw TOS and had Kirk, Spock, McCoy, etc. First Contact likewise for people who enjoyed TNG's run, which only ended two years before it was released. Knowing that Paramount, as a firm like any other, cares most about sales/revenue/profit, then this would have been the central reason for the TOS and TNG films.
