What would be the benefit of a lighter flywheel?

Absolutely not true. It would reduce parasitic losses involved in the rotating the driveline (and in the other case a heavier flywheel). Ultimately it would actually improve tq and hp readings at the flywheel.
It will decrease inertia, which is not the same as torque.
