For what it’s worth, ENT is set around 2150, SNW around 2259, TNG starts around 2364, and PIC around 2399. In my mind, ENT is pretty far removed from the SNW/TOS era that you’d say is well covered. There’s a lot of “untouched” canon to discuss, like the Earth Romulan war. So long as temporal wars are forgotten, I’d be excited to see more ENT stuff.
But I also agree that just going forward into the 25th century would be nice too. Ideally for me I’d prefer to see a clean break from the TNG/PIC nostalgia characters: just the next, next generation, with a new captain and crew.
I do like Jeri Ryan’s Seven a lot, and would love a Captain Seven, but there’s something to be said for just starting the new thing and building the next big dynasty of trek, rather than borrowing characters.
