Good question. Energy recovery from a spinning down load is feasible,
but not in this manner, and the return on investment is minimal.

A capacitor stores "DC energy" and the motor makes (if it makes
anything at all) AC energy. Converting AC-DC-AC is expensive, and

The energy recoverable  as a % of all used is trivially small  in
almost all cases.

The capacitor costs for even modest storage are large.
