The whole ATs aren't allowed aside, you do realize that you have some holes in this premise right? For starters some of the Primarchs were doomed from the start, there was no hope of them remaining in the Emperor's service indefinitely. I'm looking at Curze, Angron and Magnus specifically. Also the Eldar allying with the Imperium? No. It really couldn't happen for multiple reasons, and yes I am saying this while knowing that they are facing some uber threat from the veiled region.
