You can't really use Samus VS Master Chief since Samus was in the pilot, so of course people wouldn't have requested her to fight Chief, because no one knew they existed at the time of its release.

And again, it ultimately comes down to if they think it would be entertaining. And they brought up at their Asylum interview that they don't necessarily pick fights that are requested, they just think they would hilarious to see. Such fights include Starscream VS Rainbow Dash, Goomba VS Koopa, Yoshi VS Riptor and Beiber VS Black.
