Fibreglass Roof Can a Specialist Copy Existing Shape?

The AM Craft Hiace Campervan model has a fibreglass "poptop" roof, specially designed to cover the side awning on van. Although there is no problem with mine at the moment, I expect the time will come to replace. I suppose I could go for another company's model, but would a yacht hull maker for instance, be able to copy this unique design. Would it be too expensive? Any ideas?

There are a few roof specialists out there that can copy your existing roof. I fell over some in the back of MMM (Motor Home Monthly) Magazine a while back.
