Have you spoken with Bill Emerson from Emerson Motorsports? I think he will agree with you on the costs of producing a speciality hardtop. The one he built for mine was 1 1/2 years in the making. In my mind (and my pocketbook) it was worth it. The sun here in Phoenix is brutal in the summers and this gives me a way to stay out of it. I then added A/C to really spoil myself. Makes it a 365 day a year car.
