I know it kinda misses the point, but how hard could it be to just build the darned thing with standard components? I would think that BT-70 would be a great size for a 29mm mount. Sandman could turn the nose cone, then you could pring out some kind of body wrap that looks just like the original, then cover the fins with the same style of wrap...but then again, that kinda misses the point!
Someone should upscale a CRLIP using a triangular shipping "tube." Then you could make the fins out of foam board, and it would be easier to print the wrap. The nosecone could be made out of thick balsa using the triangular patterns upscaled, then glued together with cardstock hinges, then exteriorly fiberglassed on the joints. The centering "rings" would be pretty simple to make out of ply or basswood, or maybe a balsa plywood.
Just rambling...
