Have your tried it? Since Python only cares about the contents of 
site-packages, copying should be fine, at least as far as python is 
concerned. I have copied pythonx.y/Lib/site-packages to 
pythonx.(y+1)/Lib/site-packages more than once.

In each site-packages, I also have python.pth containing, in my case, 
"F:/Python". packages and modules in F:/Python are imported the same as 
if they were in each site-packages. This avoids copying and lets me try 
the same file on multiple versions.

Copying does not copy registry entries or anything outside of 
site-packages. I do not know whether pip, for instance, does either.
