EDIT: I've searched around, and have found no sign of anyone ever creating a silicone stringed mini double bass. I would guess that this means that it simply won't fly as an idea.

I recall seeing a page about a bowed electric "upright", about Ashbory scale, using a piece of steel or plastic tube as the body and piezo pups under the bridge elements. Cello tuning, I think. It didn't look even vaguely like a "conventional" bass or cello, though. IIRC the builder was Belgian.
