That would actually mean for the Eldar to not be the Eldar and the Imperium to not be the Imperium.

The only instances where Imperium and Eldar work together is generally when a foe threatens both and you got the "foe of my foe is my friend". Generally those instances revolve around cooperation in the face of annihilation.

The Eldar will still have no qualms about sacrificing humans to make Eldar survive and the humans will still view any xenos as in need of being killed.

Alas as for the Alliance betwween species: Interex, Diasporex and so on, aka human cultures that the Imperium wiped out during the Great Crusade.

The manifest destiniy of the Emperor was for humanity to rule the galaxy and to wipe out xenos wherever they had sth that humanity could benefit from.
