Snape didn't make the Unbreakable Vow

Hello,
   
  I have theory that is not so far-fetched. I don't think that 
was Snape that took the Unbreakable Vow. I think that was 
Dumbledore (under Polyjuice) pretending to be Snape.  Polyjuice 
has been proven to be a good way of spying on the enemy. If 
Dumbledore took that vow, then the night he was killed makes 
more sense. He pleaded for Snape to kill him not because he 
wanted to just save Draco and Harry, he was also trying to 
save Snape. 
   
  If Severus did not kill Dumbledore, Dumbledore would have 
died and the simple fact that Shape did not die would have 
made the death eaters, especially Narcissa and Bellatrix very 
suspicious. If could have cost him his cover and his life. 
   
  But since Snape agreed (in the argument he had with 
Dumbledore) to do kill him if the siutation arises, he agreed 
to play along and continue his work for the Order.
   
  Just some thoughts. Tell me what you think.
