Most of the X-Men characters outside of Wolverine, Gambit, Cable and Domino, male and female, have no life outside of their team. It needed to be someone with their own life, own lore, own villains, probably a civilian job and supporting cast of their own as well.
Not saying it needed to be Carol, but Rogue, Storm, Jean, Betsy or Emma would have been difficult to turn into a solo character.
