If anything, I would be for a ball size change. Have the standard size be an 11". Never understood why girls play with a huge ball and the boys play with a little marble. Then when the girls stop playing fastpitch and go to slowpitch COED leagues, they use an 11" ball for the women at bat and a 12" for the men. I know a lot of other things would probably have to change if an 11" ball was used (fences over 200', possibly move rubber back), but I think it would be interesting.
