[40k]Wonder if the remaining Eldar Gods(don't remember what they are called) could revive the Emperor of Man. And after doing so, convince him to help them kill the Chaos gods. It sounds ridiculous, but keep in mind, there is an Eldar prophecy saying that their gods will one day return and defeat Chaos. Though that sounds outlandish, remember that the Elder are powerful psykers. They can foresee the future.
