If the feed to the sub-panel has 60 amp breakers in the main panel, then #6
AWG feed to the sub-panel is required by the NEC code. That you estimate at
this time you do not ever use more than 20 amps out of the sub-panel has no
bearing on the ampacity requirement for the sub-panel. A subsequent
occupant of your property may chose to expand use of the sub-panel to the
degree implied by the main panel breakers for the sub-.panel. The code is
intended to protect future occupants as well.
