As said in both rites, I believe, your statue of your adult self cannot be altered or else the mind will reject the body and problems will arise. What gets me curious is... what problems?

I'd think that:
A) The mind would completely rip itself from the body and be stuck as a wandering spirit like Taengee or Hestha.
B) The mind would get stuck in the body but not mold itself with the body as it should, causing you to become much like the Entombed Will.
C) The mind would refuse the statue's alterations but accept the rest, so that the dragon is normal but has no alterations.
D) The mind refuses the alterations completely and tries to revert any alterations, but fails and cripples any part of he body related to the alterations.

What do you think?
