I like that we're brainstorming, here, but sorry, this makes zero sense.
What are Necromorphs? Hideous, mutated humans that swarm you like claw-wielding zombies.
What are the Voteless on Illuminate worlds? Hideous, mutated humans that swarm you like claw-wielding zombies.
It'd be like doing a Terminator crossover for the fourth faction and having you face T-800s. Or doing a Starship Troopers crossover with bugs. It'd just be plain redundant.
