HAHA...I can just reach it and on some roots it hurts a little. The point was from G it's a mirror. If you went to minor you could do something like keep the G and then an Ab triad on the bottom and a Bb major on top. Two traids a fifth away from the G. That kind of stuff. You don't use it a lot, but to be aware of it and hunt for it can take you to some interesting places. You can sit around for hours playing with that stuff....and it's not always about the piano. This stuff could be for tpts,bones, ww's, etc.
