That was kind of the point. The original idea that I still have notes of was actually to remove the Chaos threat through some means and have the Imperium focus on the Serathi. The Fallen Legion was a HUGE compromise from that perspective. But that's getting off-topic. The fact remains that Guilliman remained pure until the end, so resurrecting him to be a Chaos Warmaster is a bit far fetched. I'm not saying that the Fallen Legion can't have that goal, but its unlikely at best.
