I'll see if I can find my joystick template and whip something up today-ish for you. You'll have to tell me if the underside of the CP won't handle the spacing, though. I had that problem - after screwing the rings onto the buttons, when I got down to the bottom, they started hitting each other and I had to fiddle for quite a bunch to get them all snuggish. I believe I fixed it with my layout template, but I recommend drilling a test panel, and 9x6 is pretty easy to replace.
I'll .jpeg it for you and send it when I'm done, should be today or tomorrow.
