That is why i feel the book is hindered with the multiple crisis that have not been addressed.I think the first 8 or so issues of the 3 team X-books have been playing catch up to what we have now and they have not been able to identify themselves as what route they will take because they have to hint at off panel details that can not be further explored without giving away to much.
I believe once we get through this initial shock of what happened 8 months ago we will see a book similar to Astonishing.
The idea of Lemire on a small X-force style team book with some of the character you mentioned would be something i would pick up.
