Someone with enough knowledge about how Python windows installs work and a rudimentary knowledge of WISE should be able to work it out so that the win32 distribution is willing to let you pick which Python to use if it sniffs one (or more) out on the target system.
What about compiling all the extension modules for the right version of python?
Realistically, we would have to require a certain version of Python be installed in order to use an existing installation. I think the real goal is to make it easier to use your own (correct version) Python install rather than to work magically with any Python that happens to be around. We should also make it easier for win32 to compile the extensions if they want to do something fancier than our installer supports.
