You guys are funny. go to a fibreglassing shop, tell them what you want, draw/bring pictures if needed, get them to make a practical kit. Voila. no more crying about no practical kits. Then patened the mold, make millions, blah, blah, blah. too much whining, not enough action.
(p.s. sorry if I sound rude, I don't mean to be. This is just what I'd do)
