I am specifically trying to design a shoe insert (just the heel part)
but the problem is more general. How to create a shape with a
curved/lofted/organic 3D surface on top of another (but different) 3D
surface attached together at an arbitrary 3D curved outer boundary

I think hat the BOSL2 plot3d() could create the two surfaces. Not sure
how to attach them along the boundary, unless the two functions were
coerced into coinciding along the boundary.

If anyone has tried to tackle something like this, I would be curious to
learn how you thought about it.

BOSL2 skin can connect two arbitrary curves. That might be able to makes
the side of your shape.

Thanks! Right. I was more worrying about varying the thickness of the
resulting shape to taper near the "side" curve. I will need to play a
little bit.
