It's certainly possible, but from everything I've seen and heard about this leads me to believe that they're going to go in a much less literal and more existential direction. Less of a quest to resurrect her dead boyfriend and more of a crisis of character, identity and perhaps even an uncomfortable look at mental illness.
When it comes to suffering personal loss, Wanda is arguably equal, or even a notch above Thor. Not just Vision, but her brother, their parents and pretty much her entire country and everyone she ever knew that wasn't a superhero or a psychotic robot. I mean what happens when someone that powerful starts to loose their grip on reality?
I guess that's a very roundabout way of saying that I think the more interesting story isn't about Vision, but about Wanda.
As for how it'll tie into 'Doctor Strange', I foresee two main possibilities: -
1) She's some kind of apprentice to better control her "condition", or at least understand it better. Maybe some kind of mystic rehab aver the fallout of whatever goes down on the show, or it may be as simple as she's moved into the sanctum because it's the only place on Earth and possibly in this universe where she's safe from herself and perhaps, everyone else is safe from her abilities.
2) She completely lost her shit, is tearing up the multiverse and is the main antagonist of the story. The twist there is that Mordu get's to be all "I told you so!" and may even be "helping" Strange. That doesn't make Wanda a villain exactly, but I can see it being something of a battle for her soul.
You basically just described the plot of Dark Phoenix. Just throw in alien Jessica Chastain and Wanda accidentally killing someone who wants out of the franchise and you're there.
