Where your methodology falls flat is that the 'experiment' you're performing is fictitious, it's not based on real numbers, nor is it based on the theory.

A real world experiment could be to shoot at f-stops from wide open to f/22 with for example 5D and D800 (using a good lens, the same if possible) , and see at which f-stop the diffraction starts to be 'clearly visible' at 100% view. My guess is that the resolution limiting effect of diffraction will become visible at a larger aperture on D800.

Potentially. Though you'd really want cameras with a wider range of pixel counts. Ideally covering 2 orders of magnitude of linear resolution, or 4 orders of magnitude of pixel count. It would be a struggle to meet those conditions and keep everything else equal.
