Saying he wants to insert if deeper is a farce that ignores the crossover is pretty dang base level and that we'd lose more than 80 percent of our current assets and be nigh on unrecognizable if it had never happened.
It also fails to answer the question with respect to that situation.
Ignoring the nature of the warp and the techno bale inherent to of the settings involved that means they can glom.

Serial critical fail happened which meant we needed a to challenge a primarch, and Eldar battle group, and a horde of or on a space hulk.
This threat was a bunch of soul devouring g interdimensiinal super predators leaning on the darkness emotions in people's souls so they were effective on everything and everyone including the demons. Hearltess. We manage to bust the incursion and stop the run away super accident but not before Malice learned the trick and used it to go from nothing to nightmare.
Delaying the chaos god he oppose cause they cast him off.
We also got replicator and an alliance with the Eldar and super magic crystal which have exploded our growth curve and are basically the sole reason we're a Le to expand as we do and shut down chaos.
There was much acrimony that the heartless and rhe tech basic means chaos is fucked for the near and moderate future towards us in El exchange for and even harder endgame so the gmnin magnamitt is letting go us change that.
Malice either wins and we deal with malice cults a later game hard mode and the need to develop anti Heartress tech which are crystals which we use for everything anyway. Possibly more chances to play chaos against other things as a possible faction more than always chaotic evil.
Or malice just becomes peer and we deal with 5 chaos gods.
Or they somehow fiat win and we deal with having to fight. Chaos more in the mid game and deal with their canon position of always fucckng shit. If in a stronger position.
