has anyone ever thought of just immersing the whole amp in mineral or
transformer oil?

Years past, I worked on many water cooled tube type
amplifiers/oscillators. Compared to those, water cooling a SS amp is
outlandishly simple. Route the Cu water tube through a milled slot
in the heat spreader. The most complicated part is how well you want
to monitor the water flow and temp. Typically a restrictor is placed
in the input line and the pressure is measured on both sides of the
restrictor. Due to the heat spreader being at chassis ground, heat
sensord can be directly attached to the spreader plate.
This has the advantage that a finned cooler can be added, so if the
water flow stops, the amp can still be fan cooled
