The only thing the X-characters have in common is *usually* a universal hatred from the vox populi, but other than disenfranchisement, each character has a very different story arc individually.
The thing is they all fall in X-Men category. Not every Iron Man movie falls into Captain America category, Thor category, Guardians of the Galaxy category, Ant-Man category, Inhuman category. Even if they all appear in the Avengers movie, people could easily them as their own thing with their solo movies especially if they haven't appeared in The Avengers.
The solo movies for the characters that you said would have to rely on the X-Men brand. And spin-off movies and solo movies would only work for so long.
