Already been proposed. Template with the balls too far apart so nobody's frozen.
First shot after the break must be a push out. That makes both the rack and the break nearly irrelevant.
I have wondered how a rack with huge gaps would work. Maybe 3/16". I suspect that Shane and Corey, a few more that work on the break, would have it doped in short order and the other top players would copy them. I have also wondered about the game the Mexicans seem to favor with all the balls arranged around the rails. Looks like a drill though and I hate most drills. So far the best solution I have found is snooker.
