Okay, here's how I would do it.
I'd have Voyager actually start building some friends and alliances due to a common enemy, then discover the possibility of a way home. There'd be the build up to some titanic battle which Janeway knows her allies and friends can't survive without Voyager, but the window of opportunity for getting home is small. The series would end much as it began, with Janeway making the choice between the death of civilizations and her ship returing to Federation space.
The series would end on a black screen with the words "Voyager never made it home."
