do you think we’ll ever get a Spider-Man or X-Men movie with Dracula as the villain

No. 

First, Marvel’s Dracula would probably run into legal problems with Universal’s Dracula. 

Second, I think there would be intense worry that Dracula would pose too great a problem of tonal or thematic clashing with Spider-Man or the X-Men.

Third, they’ve got much better villains in their back catalogues who are more natural fits.
