Flattening a Spherical Segment...

I know I know, it's theoretically impossible.  But that dosn't stop a client from wanting a material pattern to stitch a ball from 5 equal segments of the sphere.  I can brute force the approximated pattern from AutoCad (ouch) or I was hoping I could create the sheet metal equivalent using the form tool.  So far no luck.  I'm assuming compound radii are not recognized.
