If an amplifier produces x watts at 8 ohms and y watts at 4 ohms, is the 6 ohm power simply (x + y)/2?

Tube or solid state?

That would do in a pinch. You would get something in between the 8 ohm and the 4 ohm output power, so to speak.
To get more precise, it really depends on the circuit design of the output section and what its characteristics are.

One of my heads is a Markbass Little Mark 800, which is rated 500 watts at 8 ohms and 800 watts at 4 ohms. I'm trying to guesstimate whether it would be ok with a 600 watt 6 ohm cabinet. Using my OP formula, it would be 650 watts at 6 ohms, which is close to the cabinet's rated capability. It's also unlikely that I would ever use that much power anyway.

I’d think you’d be fine.

If you are measuring speaker resistance in ohms the 6 ohms is about what 8 ohm Impedance Speakers typically read. 4 ohms will typically read 3 ohms Resistance as Resistance in just one of the 3 parts of Speaker Impedance (Inductance, Capacitance, and Resistance)
