Thanks everyone for the awesome support. Attached are some pics of my existing setup.
Given all the options, it seems easiest to add a small Siemens subpanel to the right of my existing Eaton sub panel. Applying the suggestions here, I could replace the existing Eaton 20A GFCI powering the pump with a 30A non-GFCI breaker and use it to feed the sub panel (connected with 10/3 I assume). Then I could feed 12/2 from the Siemens breaker back into the Eaton sub panel and connect it to the existing 12 gauge pump wire.
Anyone see issues with this approach?
