"Spyder" style top for 986?

[j.fro]

I've been thinking about this as well. I've got a hardtop, so I removed the soft top, motor, transmissions, etc and lost about 70lbs. I'd like to weld in a "back-half" cage, and I think that could be used to give shape to a lightweight soft top similar to the Spyder's. A zipper or some internal snaps along the back edge would work to hold things together and keep most moderate rain out. Sealing around the windows would be the real trick.
