Sounds nice, but my gut feeling is that you wildly underestimate how far people will go to work around anything that could change their beliefs.

As a deeply religious person this might come of as really ironic and the irony is not lost on me: quite the contrary and for that reason I've thought about it multiple times.
The man agrees, "Yeah, corpses don't bleed."
The doctor pokes him in the arm with a needle and blood wells up.
The man looks at his bleeding arm in astonishment and says, "I'll be damned! Corpses do bleed!"
(This is a true story. I think it's in "The Man Who Mistook His Wife for a Hat" IIRC.)
