It'd be nice, but Star Wars is hardly progressive enough for it. The first Star Trek series had a black woman heavily implied to be in a relationship with a white man (a television first!), and featured her as an important central character, as well as gay side characters (a later series even had a trans character as a love interest!) - Star Wars had a racist Rastafarian caricature act as the "comedy relief" in the form of (the much hated) Jar Jar Binks.

So, even with J.J. at the helm, well... It really doesn't seem likely. Though stranger things have happened; Just look at the survival of Poe!
