I don't know about the
whole series, but here's how I'd reformat the first 4 seasons into one season in order to create a sort of narrative "story arc":
1. Caretaker (series premiere)
2. Paralax (establishing Torres as engineer)
3. Phage (the Vidians, Seska)
4. Prime Factors (Carey, Torres, Seska, Janeway, some Starfleet/Maquis tension)
5. State of Flux (Seska leaves)
6. Learning Curve (essentially the "end" of the Maquis arc)
7. Elogium (Kes begins to mature)
8. Cold Fire (Kes continues her growth; we meet the female Caretaker)
9. Maneuvers (the Kazon arc continues)
10. Alliances (ditto)
11. Meld (introduction of Lon Suder)
12. Lifesigns (Kazon 'traitor' arc; also incorporates the Vidians)
13. Investigations (ditto; ends the traitor arc)
14. Resolutions (an end to the "Vidian" arc; as well as Janeway/Chakotay)
15. Basics 1 & 2 (the end of Kazon arc, as well as Seska and Lon Suder)
16. Warlord (the Kes arc continues)
17. Fair Trade (Neelix's function as an alleged guide ends)
18. Scorpion 1 & 2 (arrival of Seven Of Nine)
19. The Gift (Kes departs, leaves Voyager with a 'gift' of being propelled ten years closer to home)
20. The Raven (Seven of Nine character building)
21. Message In A Bottle (re-establishing contact with Starfleet)
22. Hunters (Hirogen arc 1)
23. Prey (Hirogen arc 2)
24. The Killing Game 1 & 2 (end of the Hirogen arc)
25. Hope And Fear (series finale; ends of a happy note of Voyager being 300 light years closer to home)
Undoubtedly it isn't elegant and probably still misses some important bits, and the resolution of "Hope And Fear" is obviously still open-ended. But I
think on the whole it'd be a internally-consistent set of episodes for a single 'season'.
