In response to the next-to-last question, absolutely yes to an X-23 movie. Besides the fact that Daphne Keen was excellent, you basically have a character who was born as an experiment to be a killing machine trying to have a somewhat normal life (but, at least in the comics, unable to). As for bringing back Jackman, no flipping way! That ending was the equivalent of Cobain screaming the final refrain from “Where Did You Sleep Last Night”: if you’re gonna go, you go out leaving everyone breathless.
Oh, and whoever decided to include “The Man Comes Around” in the final credits is a genius
