Campaign Versus?

I’m pretty sure eighty people would have had this idea before, but I think it would cool if we took Reach’s firefight versus, and added campaign playlists/or separate missions that could be matchmade (Kinda like Spartan Ops in Halo 4), except some players would be Elites tasked to kill the player. That’s pretty much it. Obviously that would be an optional mode separate from the Campaign mode, and maybe if it was focused on some of the more linear sections, we could put that underneath the firefight category.
