@pinkpanda,
I don't know Xris, but tales like this belong probably more in books than in movies. In movies one can hardly escape the gore, as a book this could be a weird fable with surrealistic and psycho-analytic aspects. Besides I hope the credits mention the source of all bizarre transplant stories: The Hands of Orlack. From the Wikipedia:
"A concert pianist, Paul Orlac, loses his hands in a railway accident. Replacement hands are transplanted onto him in an experimental procedure, but the hands are those of a recently-executed murderer. From now on the pianist is tortured by panic attacks and irrational fears. He believes that with the hands of the murderer he has also gained the murderer's predisposition to killing. Strange signs and bizarre threatening letters reinforce these fears. When his father is killed, with whom he was on bad terms, the pianist is suspected of the murder. He only finds peace by clearing up the plot."
And of course there is Frankenstone (wh?t hump?), but since the Mel Brooks movie it has become difficult to take that story seriously. I think that's a.b.normal, no? ;-)
