Very good idea. I have also thought about doing this. I don't know any of those specs so I cannot directly help you, but my $0.02 is this: Find somebody who owns a GMR set that is not currently in use and ask if you can borrow it for a few $$. Immediately have somebody at your office do a 3-D CAD model of it. If the materials are not explicitely known, have an X-ray spectroscopy performed to determine composition.
