Almost sounds like it'd be worth trying a method similar to an overnight soak in a parts bath. If Seafoam is basically kerosene, I wonder what would happen if a person drained the oil, removed all the spark plugs, and just filled the cylinders with kerosene to give the rings a chance to actually soak rather than just be subjected to a mixture of oil and Seafoam?

Or to take that even a step further, I have no idea how much kerosene would be necessary to achieve a fill level from the oil pan up high enough that all the rings in all the cylinders would actually be able to soak, or if that would even be enough since some parts still need to be scrubbed after an overnight soak, but if you're using a gallon of oil between changes, could it really make things any worse?

I'd add a disclaimer though that I've never looked at a VX motor straight on to even eyeball how high a piston at TDC in a cylinder would be in relation to the rest of the motor, to get an idea where that high a level of kerosene would take kerosene in the rest of the motor when the fluid leveled out, so that kind of soak might take kerosene to parts of an engine where it shouldn't be.
