The problem is that citizenship in ancient Greece was usually tied up with military service: basically, the idea is that the people whose lives are literally on the line defending the city should be the ones who get a say in how it's run. Since women didn't fight, in Greece or in virtually any other ancient society, there was no perceived reason to let them vote.
Now, you could probably get a few female voters with the right POD, but it would be easier to do with oligarchies than with a democracy like Athens. Citizenship in oligarchies was, of course, tied up with property qualifications, and polities with a property-based franchise have sometimes had female voters even if women as a sex weren't enfranchised (e.g., in colonial America). So if you change Greek customs such that women can own property in their own right (which they generally couldn't outside Sparta, IIRC), you might see a few rich women voting in the more oligarchical city-states.
