The big problem is if they actually make Shuri the Black Panther, there’s going to be a contingent who will raise holy hell about T’Challa returning and “sidelining her”. If she gets the role people are going to expect Marvel makes her
the Black Panther going forward, like how Sam is taking over as Cap. Depending on how BP2 handles Chadwick’s passing I may feel more optimistic about the chance of a new T’Challa. Secret Wars is the perfect way to soft reboot the MCU as needed.
As for the Storm romance, I’m over it completely in the comics but I wasn’t 100% opposed to it in the movies if for no other reason that the BP is the equal (if not the superior) of the X-Men franchise on the film side which is not the case in the comics. But you gotta understand, if he’s dating Storm in a movie
that’s it. That will cement Storm as
the love interest for T’Challa and you better believe the comic side will have to synergize given how Shuri was deaged and turned into a copy of MCU Shuri. So if you guys are ok with Shuri being cemented as his Lois/MJ/Catwoman, the number 1 LI, then yeah they could do it. But I’d personally prefer someone else
