Yang cannot be the Fall Maiden, because Amber is the Fall Maiden. Cinder stole the power from Amber, but Amber still holds the rest of it because she hasn't died yet. If she were to die, then Yang may become the Fall Maiden if part of your logic holds true, but she isn't dead, merely in a coma, so Yang cannot be the Fall Maiden.
