My reasoning for having Janeway not be the captain from the get go was to evoke something similar to President Roslin (I did like SOME things about nuBSG). Maybe I should make the real captain of VOY also be a woman who ultimately ends up killed when they get to the DQ.
Kes, well it would require like 3 actresses but I think it could work. Plus she'd stop aging by S4 since her emerging powers would prolong her life.
3 B'Ellanas would resolve eventually, while giving Roxanne a chance to flex her acting chops and give the split screen tech some workouts too.
