I like to think that Tyranids would be welcomed with open arms. They seem to embody all 4 Chaos Gods.
Vicious in melee, willing to throw critters into the fray regardless of the death toll (Khorne)
Consume and regenerate the fallen (Nurgle)
Utterly fearless and under complete mind control (Slaanesh)
Wily little tricksters with lots of unorthodox methods for winning (Tzeentch)


I think there would be a big old party as they frolicked together in the eye of terror. I mean cmon. Whats not to like?
Tyranids can consume all the possessed humans and such they like, the demons have a perpetual regenerating foe.
Endless war!

Man that would be great.

Perhaps a new Chaos God would arise from the conflict between WarpSpace and ShadowintheWarp space.
