Both the A330 and A340 are FBW. This means control inputs will be made by the FBW system as soon as the aircraft starts to roll and so if we assume both FBW systems are equally competent the two aircraft will both subsequently respond in the same way to the same gust regardless of any roll inertia differences. That is what FBW is all about.
