I don't see why a Human-Covenant alliance is so unlikely. You can even make a small alliance in the game. In the level 'Keyes', there's a part where an elite is in a stationary gun. If you run right past him and start killing the flood, he kills the flood instead of you. Once the flood are dead, he won't shoot you, you're his ally.
So maybe, if both Humans and Covenant face destruction from a much stronger race in Halo 2, they may ally.
