If the Emperor died though, i think that the Imperium would shatter, as every psyker would notice if the astronomicon went down, and you just cant shut up that many people. humanities collective spirit would be crushed and then all kinds of shit will hit the fan. So the Primarch that returns first will (if the emperor died before his return) find the imperium even less organised than it is at the moment, and probably needs to start a new empire somewhere, and start the Great Crusade v.2 It's even worse than that, if the Eldar are to be believed.

Apparently upon the Emperor's death humanity's collective belief in him would cause reality to rip again and create a new eye of terror and birth a new chaos god, which would probably plunge the entire galaxy into the warp.
