What would happen if you AK'd a dead body?

Lots of people have pointed out that what happened when Snape AK'd
Dumbledore on the tower was not your standard result.  I've already
got a theory that Dumbledore was "hosting" Voldemort after the visit
to the cave - that he himself became the Horcrux.  What was happening
to Dumbledore from the return to Hogsmeade and then the trip back to
Hogwarts?  He seemed to be *rapidly* weakening - Amycus says "He's not
long for this world," and it seems possible to me that Dumbledore was
actually dying as they stood on the tower.  Even just during the
conversation with Draco, he became so weak he couldn't stand anymore.
 I wonder if at the last moment, his soul was leaving, and if all that
was left was the parasitic Voldemort still in his body.  His last
words are to Snape, and Harry definitely says that he is *pleading*. 
Well, as everyone agrees, Dumbledore would NEVER plead for his
life...but I'll bet Voldemort would.  Faced with death, I think
Voldemort would do or say ANYTHING. So maybe what we heard wasn't
Dumbledore pleading with Snape either to save him, OR to carry out a
previous agreement.  Maybe it was Voldemort pleading with Severus to
save him, and Snape's revulsion and hatred was his reaction to that. 
Maybe that's why Dumbledore didn't look like he'd been AK'd - because
by the time the spell hit his body, he was already gone.
