And Tuvok, as the new Capitain of Voyager if Janeway was definitively out, would be the most logical choice. He is the oldest Starfleet senior officer serving on board and his legitimacy (authority & experience) is unanimously recognized by all, that they are Starfleet (more 2/3 of the whole crew) or Maquis (a little 1/3). Plus, he is officially ranked Lt Commander (and after Hunters, entitled Commander), contrary to Chakotay, who was granted by Janeway, the
provisional rank of Lt Comm. (after to have offically lost it by resigning his commission to join the Maquis) and became
Voyager's second-in-command for only the time of their "little" escapade in the DQ.
So, if events had to turn badly and Janeway was in incapcity to hold her role of Captain, the wisdom would command Chakotay to propose to Tuvok, at the same time, the seat of captain* (because of his legitimacy & his experience and respect he gets from everyone) and his services as XO (he seems to appreciate this role). And Tuvok, to accept the double offer, because it would unquestionably, the better for everyone aboard => the change in the continuity, I guess.
.
But a thing is almost absolutely sure, the relationships between himself and Tuvok would be
very formal but not less conflictual!
-> contrary to Janeway, Tuvok will be guided by the logic and not by the emotion).
(* I don't think that Chakotay would take the risk of refreshing an old conflict (that he'd certainly lose quickly or on the duration, besides) between Starfleet and Maquis, in trying .a coup de force to prevail himself as the new Cpt).
About Tom Paris, as First Officer... Nope. he wouldn't be interested and I don't think that he'd be too happy not to be associated with too much responsibility. His main goal remains to enjoy life in doing what he loves (piloting & making holoprogram), while being a good man (husband and father-to-be, friend). However, he could be a good (and unconventional) XO and even Cpt...
