Actually if you'll go look for the US analysis of Kogo's Zero you'd see that is exactly what happened to the A6M2. It would only roll with the engine torque. Near complete aileron lockup over 250 mph.
The N1K2 uses same tail structure as the A6M5, with a taller vertical stabilizer and rudder, and a very simular wing structure, in dimensions and shape, the main difference being a different aileron set up, and a thicker cord towards the wing root to hold the auto-flaps.
