Currently, Danai Gurira and Lupita Nyong'o already have roles in the Marvel Cinematic Universe (MCU). Danai Gurira is Okoye and Lupita Nyong'o is Nakia in the Black Panther film. Once Disney's acquisition of Fox is complete this year, the X-Men/Fantastic Four will join the same cinematic universe as the Black Panther film. It would not make since for either of the two actresses to play Storm because they already have roles in Black Panther. Hope this makes sense.
