Basically what the title says. What if on that fateful day back in high school, due to trans-dimensional temporal shenanigans, synthetic Kryptonite, and skipping lunch, the spider that gave Peter Parker his normal powers was crushed a split second before it could chomp down on him as Clark Kent daintily nipped at the Pete instead, giving him the proportional powers of Superman?
Assume that he gets powers equal to the most recent version of whichever Superman bit him. In no particular order:
1) Golden Age
2) Pre-Crisis
3) Post-Crisis
4) JLU
5) Nu52
6) Smallville
