I don't doubt that one day in the far future scientists will be able to make a Frankenstein's monster out of spare parts but what about your soul? That would be gone as soon as you have,even if it does develop one who's will it be,the donator of the heart of maybe it's the brain,what's the point of freezing your head if it has no memory or soul? How do you explain to the big man upstairs that you now want to go back and blow your wedge on booze n birds before somebody else does?
