I would find this extremely interesting. Cables make a huge difference in my system, and I have been experimenting with DIY to better understand how materials and geometry affect the sound. It would be a complex endeavor, and expensive, but for the right person these are small hurdles.
As others have mentioned, the trick might be accurately classifying the materials found in the cable, but some of that could be taken from the manufacturers claims. Geometry, gauge, wire base metals, wire plating, wire spacing, dielectric material, dielectric volume, insulation material, terminator mass, terminator base metals and plating, shielding, grounding, all of these can affect the sound.
I would put some support towards such a project. Great idea.
