[WH40K] What if every single human psyker in the galaxy killed themselves at the same time?

The God-Emperor of Mankind was supposedly created by the force of a few thousand psykers committing collective suicide in order to reincarnate as one being. 

In 40K there are *millions* more psykers than when the God-Emperor was created, what if they all killed themselves trying to recreate that event and make a second, even stronger God-Emperor of Mankind?

What if they somehow had knowledge of the *exact* procedure the ancient Shamans went through to create the GE, and all gathered on a single planet to follow this procedure?

They wouldn't be able to coordinate as well as you think, those deaths would fuel the Chaos Gods because Psykers don't have control over regeneration like the Shamans did.  So if they all killed themselves, we'd:

* Lose the Astronomicon.  RIP Imperium
* Give power to the Chaos Gods.  RIP Imperium
* Never hear a blind man yell "WITNESS YOUR DOOOOOOM" again.  RIP Everyone.
