Amiable Dorsai:
Too easy.  If I were writng it, Kreacher would have given the locket 
to Narcissa Malfoy.  Narcissa would hold the locket hostage for
Draco's life, after Draco's failure to kill Dumbledore.

Then Narcissa, at least, would go to the Order for sanctuary, again
using the locket as a bargaining chip.

Then it would get complicated.
