With Ms. Marvel retcons she is no longer an inhumans, this marked the final straw for the prominent inhuman. Since Marvel has the full right for the X-Men, the inhumans franchise was thrown aside and no writers was interested in using them again. So the best scenario is sell the right to other property like IDW, Dark House or Dynamite. Maybe those comic companies would be interested in using them by reinventing them into something unique and different.

Your thought about this idea?
