You can get a good % of regen if you slow down slowly, once the brake pads have to touch the rotors, you are throwing energy away.

Unless these batteries can accept charge faster, their extra mass won't be offset by more regen.

Except for the risks inherent in large quantities of mechanical inertia stored in a rotating mass, flywheels might seem an attractive option for rapid energy exchange.
