X-Men Blue is the best book outside of Astonishing. Y'all need to let the O5 thing go.
Rename X-Men Gold to Uncanny, find a new writer. Put Soule on "X-Men" with his Astonishing team. Rename X-Men Blue to "X-Men: New Mutants" and keep doing what the book is already doing. Cut Gen X because it's not firing on all cylinders and I don't care about the cast at all.
Cancel Cable. Cancel Iceman. Cancel Jean Grey. Stop making solo ongoings focused on one X-Man. If you want to do minis, great. X-Men is about the interactions. ALL TEAM BOOKS ALL THE TIME UNLESS YOUR CODE-NAME IS WOLVERINE!
Speaking of Wolverine: One Wolverine book with the OG in space trucker mode, OML stays in X-Men, Laura keeps her book, and Weapon X is the catch all Wolverine book with every Wolverine doing Wolverine shit.
In short:
X-Men (flagship, big shit, all day, every day)
Uncanny X-Men (Weird shit, magic, other dimensions, go wild)
X-Men: New Mutants (O5+alt reality X-Men)
X-Force (Weapon X+Cable)
Wolverine: Space Trucker
All-New Wolverine
Weapon X (All Wolverines ever!)
Done.
