I actually did see some of that logic. The book is supposed to be about the resurrection protocols and making sure they don't make a duplicate of someone who is still living. That brings up ideas about the afterlife and a more poetic/spiritual take. A lot of those characters have resurrection stories of their own, too.
That said, I think exploring Kyle and Jean-Paul's relationship is interesting in the Krakoan context. I don't care about Hope or her generations, so I'd skip them(Prodigy is the best of them and his powerset is good for this). I don't really like Polaris or Rachel, so I would skip them too, but in terms of the premise, Rachel's hound background suits this, and Polaris is largely associated with X-Factor, so that tracks.
I do want something for Monet and James(Warpath), but maybe they'll end up with Storm under Vita. It also makes sense to have doctors hanging about to make sure all the bodies are turning out correctly, so the Cece and Nemesis(even if I never liked him) seems legit. Eyeboy is my only real objection to this official cast, though his powers could be interpreted well in an investigative narrative.
