I'd be interested in making such a thing, not sure I'd like anyone else's take on it though. It would be new though, and I think feature the kind of Not!Magic we've seen... I also think they won't do it for fear of stepping on Dr. Strange's mystical toes.
Quicksilver has always played second fiddle to Wanda. There's a reason she's fairly popular in the fan community, and he's... not. He's just always kinda there, being a prick, whereas she developed a ton of friendships and relationships with others and evolved as a character in pretty significant ways.
The problem with a SW movie is that most of her solo material from the comics is convoluted nonsense, so they'd basically have to start from scratch for a movie. Which is certainly doable, but I don't know if they'd do it
