[Warhammer 40K/Star Wars] Can the Galactic Empire resist the Eldar of the Craftworlds?

A bored, omnipotent and capricious entity decides to send the Eldar to the Star Wars universe. With a simple snap of a finger, all Eldar Craftworlds are teleported to the galaxy during the height of the Galactic Empire, positioned close to each other.

This entity then transmits a psychic message to each Eldar, promising to free them from Slaanesh if they manage to overthrow the Galactic Empire and destroy Coruscant. The Eldar, after much discussion, decide to believe in the entity and agree to destroy this Empire, although they know little about the universe.

Finally, the entity teleports to Palpatine and grants him all possible knowledge about the Eldar, including their history, biology and technology.
