They already did that in STO. Half their audience will be expecting that. That's not actually a bad idea. Would be a hell of a plot twist, although justifying it would be incredibly difficult.
Given Voyager's emergence at the end of Endgame and V'ger being a Borg probe, the heart of it seems quite a natural spot for Janeway to put her ship. And if Admiral Janeway happens to be still on board, Kirk will be happy to have another rogue Admiral with a hefty ship to deal with.
Take one of a dozen failed attempts to get back to the Alpha Quadrant, and you have the potential for Janeway's ship falling into a black hole and coming out were the Prime Universe's Voyager 6 ended up. Janeway's crew is perhaps killed by radiation and the machines try to figure out USS Voyager from the computers. Probably mash up some things from the main computer, captain's log and other entry (perhaps even have issue with the Doctor and 7of9's remaining Borg bits.) And simply build a better ship around the crippled Voyager to fulfill its two goals. The ship was built as an explorer, so it would follow the Starfleet motto to seek out new live forms and all that...but also follow Janeway's mission...to get back home. (If Katie is hot stuff now, imagine V'ger using her image in place of the Doctor's to communicate instead of Ilia. Because things are not equal, V'ger N'656 heads for home...at the wrong time and in the wrong universe. Stuff happens and by the time it gets to Klingon Space, it has the massive cloud for reasons. Its weapons, regardless of it they are upgraded by the machine race, would easily be 100 years better than anything the Klingons or Starfleet has. Remember what USS Defiant NCC-1764 could do to NX-01 era ships. Now image the same thing happening from USS Voyager to the Constitution era. Depending on just what tech difference the new films have verses a Prime Universe Voyager remade for a new film V'Ger.
In context of keeping it so the Machine planet, and thus "V'Ger" still behaves at it did in not understand the "carbon units". Having Janeway and her crew alive on ship...when that tells a different story where "V'Ger" is not really possible.
And it's returning to the Creator only because it was recalled "Where is the Creator?" "The Creator is no more. They're Chrysler now." *Earth is destroyed*
I think TMP would have been a different proposition if it were directed by Ridley Scott or Stanley Kubrick. Anything where it's not so much about action or even the dialogue, you need the film to be an atmospheric experience. Wise, god bless him, was maybe not the best choice. In any case, I was disappointed that Voyager didn't encounter "the Machine Planet". That civilization obviously has extraordinary technology. What do they think of the Borg. Would they think 7 of 9 needs full machine conversion? Interesting possibilities, but alas...it didn't happen. Stopping things like V'Ger, the Doomsday Machine, and the Whale Probe are a key part of the Legend of Kirk, so I certainly hope they are not scrubbed from his future. But except for the D-Day Machine, those things are not in his immediate future. So the next movie doesn't have to involve any of that. Ilia and Decker can certainly appear. They should both be in Starfleet.
It is still about 13 years before those events would happen from were we last saw Kirk and his Enterprise.
