I love the idea, but honestly, they should incorporate all the Traitor Legions first. I mean, we're missing a bunch: Thousand Sons, Emperor's Children, etc.
BLOOD GORGONS for sure because of there blood ritual. now if only berzerkers did that maybe kharn would stop back stabbing us! also sons of malice would be badass.
Blood Gorgons, would love to see them at full strength and team up with the thousand sons and tear apart and destroy the Space Wolves.
As your forum avatar suggests . Interesting twist on the second part of your elaboration, I wonder what the Crimson King would do if an opportunity arose...?
I want Leman Russ's face cut off and put on my chest plate and have his eyes in my hand while I watch the Wolves be burned and impaled and their hands parted from their necks and watch that ice ball of a planet hit with a virus bomb and see that place turned black for what they did to us and the Thousand Sons!!! Hail Khorsaad Gammadin and the Red King !!!
They are not "dead" and "gone" to me, they are still out there destroying all they can while their god slumbers and waits...
