Two facts pointing to the other direction:

Rim brakes are lighter than dics brakes.
Rim brakes dissipate heat better than disc brakes (but dics brakes
dissipate heat better than drum brakes).

For lightness, you might want small, thin discs, for heat stability you
want the opposite. Discs that are too small or too thin can heat up so
strong that they warp.
