Hope I'm not stepping on the toes of Bill. But PLEASE don't do this. It will cost you the plane sooner or later. Just practice until it comes natural to you. This would be like flipping a switch depending on if the plane was coming at you or away from you so the ailerons would work the same way. When you started flying you had to think about it and now you don't the inverted flight will be the same with a little stick time.
