[40k]Could the orks heal the Emperor?

If you managed to spread certain beliefs about the Emperor amongst the orks could their psychic thingy be used to heal him?

It's possible.

Hell, it's possible that the fact that the Orks think the emperor is alive is the only thing keeping him going.

However, this strategy is very impractical.

First off, there's the issue of just how well humanity *understands* the workings of the Orks' WAAAGH!!! powers.  If they can't agree on how powerful it is or how it works, convincing anyone in power that this is a workable strategem is problematic at best.

The biggest hurdle to actually implementing this is overcoming the rampant xenophobia in the high command and convincing them to use a xeno race to resurrect Big E.  Even if you managed to think up put forth a proposal thoroughly outlining how you would propagandize an illiterate race that generally only focuses on what is right in front of it at that very moment, *and* get it in front of the insular governing bodies, it is *highly* doubtful that you wouldn't just be **BLAM!!!**'ed for heresy on the spot for even suggesting using filthy xenos to revive the holy Emperor.

TL;DR - Is it possible?  Yes, depending on whose version of how the WAAAGH!!! field works is accurate.

Would the Imperium try it?  Chances are about as good as Slaanesh beating Khorne at arm-wrestling.
