Off the top of my head, that sounds like you're off in the pressure requirement by multiple orders of magnitude. The pressure used for the superconductor is enough to shatter diamond. Creating strain in a lattice like that would just shear the materials apart.

Material tensile strength can be orders of magnitude higher than compression. I wouldn't dismiss the possibility of microscopic level internally stressed materials reaching such pressures.

I also know nothing about material science so it's baseless speculation

I enjoyed this schizophrenic approach to scientific enquiry.
