That can still happen, she's the Captain of the Enterprise-G at the moment.They dropped the ball by not giving Seven "Voyager" but heck I least I saw a glimpse of what I wanted was to see Raffi and Seven together on a ship.
It would be nice to show her transfering Captaincy's to a brand new ship and let somebody else take the USS Enterprise-G from her.
But when the PathFinder class Voyager-B becomes a thing, a nice highly detailed model with some structural changes would be cool.

As far as Raffi x Seven, that can still happen, or they can go their seperate ways.
Who knows what the writing staff will do.
Not everything can look like The TOS Pilot episode "The Cage" after so many decades passing by and VFX updating.Not a chance. All I'll be doing is complaining why it doesn't look like THE CAGE and why that things named Enterprise doesn't look like the ship I love? I'll look forward to Legacy and keep my fingers crossed.
Even Gene Roddenberry prefers to update his designs and really liked the Enterprise-D / Galaxy Class when it was new. Same with TMP Refit Enterprise.
I guess you'll need to adapt or learn to let some things go.
