If you're having to add that much capacitance to your system then my guess is you are having other issues rather than just noisy motors. I'm running some of the most powerful (and traditionally considered noisy) motors out there with minimal damping on the FC and almost no capacitance without issues. A lot of the noise issues are a result of inductance in the wiring and gyro issues rather than the motors themselves. For instance, any flight controller with a built in PDB is much more likely to have noise issues due to proximity of the high inductance portions of the board to the low voltage electronics.
