Good point, if that new character is indeed intended to be the daughter of/descendant of Kitty and Peter with both of their power sets. Of course, powers have not really been shown to be inherited like that in existing continuity.
On a related but tangential point, it was never really clear how Moira knew about Kevin's body-hopping ability, considering he seemed to be in his original body during the escape from Muir Island and that appeared to be the first time he'd ever used it.
