I have to admit they look very nice in renders.

however, the cost will be too high for tube clamps. I would rather have gold plated compression fittings for a few bucks more (if that). I also fear the threads will not withstand much abuse... rendering your ~$8/each clamps useless!

who knows.. I don't want to discourage you evil I'm just not much of an optimist. If you can make this happen at the right price they will sell like hotcakes
