I could certainly do that -- and I might even be able to come up with the $2K for a set of moulds and the $200 per-piece cost except that it would be $200 times however many the foundry would need to make for the production effort to be worthwhile (that $200 price is NOT a one-off or onesie-twosie price). Then sitting on a run of manifolds taking up space (which is never free) and selling them verrrrrrryyyyyyy sllllowwwwwwwwwlllllyyyyyyyy at the price I'd have to get just to break even on the effort.
