It should be possible to parallel another 5 Farad of C by adding a DC
connector to the Gamma supply. For higher duty cycle operations, just plug
the added C into the new DC jack. For lower duty cycle, the added C would
be left unplugged.
Real estate is pretty tight inside the Gamma supply. Probably the best
attempt may be a coaxial DC jack and it cannot be accidentally reversed with
the existing Molex output connector. The Gamma supply works very well with
the K3 and the inclusion of more C would probably make it even better under
higher duty cycle operations.
