If there were a spinoff show announced after Voyager got home, about Captain Chakotay, with Paris and Kim and an otherwise all new crew (and thus missing some important characters on your list), would you have tuned in?
No! I'm afraid not. Chakotay by himself (meaning without Janeway and the rest of the gang) simply isn't interesting enough for me. I love Tom Paris, but a show about him...don't think so. I'm not interested in Tom Paris himself, I'm interested in how he interacts with Janeway and B'Elanna etc.
I'm not interested in strangers so I'd say no to a show that centered on any of them on their own.
I've said it many times now - what I'm passionate about is Voyager and the spirit of the show, the interaction between the characters I care about - not some strangers.
Why you'd think up strangers when you've got an already established crew and a fanbase for that is beyond me, but then I'm not you and you're not me, and since we obviously do not agree...fine with me.
...Janeway (at least once she dies, which is something like halfway or more through the first book). If you don't think of it as "Voyager", but as a separate story utilizing some of the characters you like, does that make it appealing?
I think, I've already answered this - many many many times. NO! I DO think of it as Voyager.
Granted, Janeway is dead...
Exactly!!!
..and that's the kind of thing that could clearly piss anyone off well enough to make them avoid a show like that, but assume for a moment Janeway wasn't dead, but just wasn't going to make any appearances. Would you be interested?
Again...NO!! I've said it...how many times now? I'm interested in Janeway, her feelings, her worries, what makes her happy, what makes her sad...and of course her interaction with the other characters on the show that I - yes I - consider essential.
I'm NOT interested in a book where she doesnt appear much. Why do you think I stopped reading?

I like happy endings and so I do dislike her death, but I don't stop reading because I'm pissed, I stop reading because I don't like what I read and get bored.
