Legion, I feel I should point out that there is in fact a genetic component to Psychic powers. It is the result of a mutation. And where Genetics leaves off the Chaos Gods will oblige. If they were to get their hands on a vessel like the Emperor's body and mind, then I imagine they would provide a suitable soul (my guess is a few thousand of their failed Chaos Sorcerers over the years), and suitably ridiculous Psychic powers.
