...this image shows Sydney and V3 in outline mode... I took the liberty of lining up thier eyes, as a point of reference, but I could have used their noses or lips or ears or chins - none of which would have made a difference in the shape disparity between them.

As you can see, even if you were to inflate them both out into a sphere, that wouldn't line up 'where' on that sphere the ears would be, relative to where on the sphere the ears ended up for a mesh with a different base shape.  So even is they had the exact same primitive shape, that still doesn't line up the individual features.  It's an interesting theory, but I'm afraid that it doesn't work.
