'course Lemond has his own issues. The whole sidestepping his agreement with Trek, selling bikes out of his garage to his friends for cash is a bit shady. (I have first hand knowledge of that issue…)
I’d second Ritte or even another custom builder (Appleman I suggested earlier does some pretty wild things), even Peacock Groove does some wild stuff with steel, might be able to help you get a functional prototype to “hang” some carbon on.
