Not reversal, but really screwed up roll control. There is a good reason you aren't supposed to modify control set-ups. It is NOT allowed by the FAA and for good reason. When you close the gap you change the air flow across the aileron because higher pressure air from the bottom of the wing no longer can flow through the gap and energize the boundary layer over the aileron. This can cause flow separation on the rising wing and sudden loss of roll force on that wing. When you change things like control surface gaps you become a test pilot flying an unproven airplane. You might luck out and make things better. You might not and end up with an uncontrollable airplane is some area of flight. The FAA just says, "DON'T DO IT". There are some things you probably CAN do to clean up the airframe, but I would NOT mess with aileron gap!
