To illustrate that transformation is not really a weird idea:
from _Earth Girls Are Easy_ the "Brand New Girl" scene and
the disguising of the visitors, or from _Tommy_ the shot which
cuts from child to adult.
A few scenes in _Babylon 5_, in the Vorlon's quarters,
show Lyta with something like gills on her neck which are
not visible at other times. Dunno whether that's useful.
Speaking of B5, for humor there's the bit where G'Kar gets a prosthetic
eye (made for humans) and complains that it's the wrong color.
