Spent way too much time agonizing about whether to rip out the VCCINT regulator on the switch board to upgrade it for a 20A module with more headroom, or keep the 12A module I had planned.

Looking at the datasheet it seems the MYMGK1R812 and 820 are pin and footprint compatible lol. It should be a drop in replacement possibly with some passive changes.

Gonna make a quick oshpark test board to validate ripple and thermal performance just to be safe but the swap seems a no brainer at this point.
