Thank you Les, thank you very much!

As for the node nerds (haha), it would have to require refraction and I think it would also have to use internal reflections, maybe requiring something else inside to help with the refraction.

That would of course require raytracing too, and I think some people would prefer to be able to render it without raytracing as well and have it look good. So your morph will most definitely be very useful.
