Not disagreeing with you, but the physical laws that describe the characteristics of this situation show that distance of the mass from the axis of rotation is more of a factor than the overall mass of the rotating object. While reducing the weight of the axles by rifle drilling has some positive gain, much more will be gained by looking at the rotating mass that is much further from the center of the axle. If I were only concerned with positive rotational inertial benefit and were considering cost, I would pay for lightened flanges before rifle drilling.
