Rather than restyle the top, I have a damaged one that I want to try making into a lightweight version (relatively speaking) like we discussed in the past. Although forming a new one out of carbon fiber would be ideal, I'll just just cut out most of the roof portion and cover it with a vent type mesh fabric. Where I'm living that would be a winter top I guess, summer is too hot for anything less than a fully insulated top and AC...winter is outdoor weather here.
What if someone made a mold to form carbon fiber roof skins, to go over a stock top with the entire top/center portion cut out? Retain the stock sides, latches, and basic framework, then glue the CF skin over the large open area left after cutting. While not as light as a full CF top, it would be a whole lot easier and less expensive to make.
