The more I think about it the more I think you might be onto something with that idea. I don't spend much time idling or sitting in traffic, so giving up a bit of cooling performance at idle for significantly more efficiency during normal driving may be an acceptable tradeoff. I would think reducing the short cycling would be better for the compressor's longevity too.
The only problem is that I'm not aware of any simple way to underdrive the compressor. To slow the compressor down, I would either need to get a smaller crank pulley or a larger AC compressor pulley. All the underdrive crank pulleys that I have seen for these engines are missing the rubber damper, so that wouldn't be an acceptable option. And unlike the other pulleys, finding a larger compressor pulley that would fit would probably be impossible since the pulley has an integrated clutch assembly.
