Sure, if you could find a place like that. Florida is not like that. Maybe the middle of Death Valley. Any place else, the only time you'll see low enough humidity would be some place where it's already cold. Below 32F, humidity tends to get hard and fall on the ground.

Could be done...either by having the evaporator very close to the vents, or insulating the ducting between the evaporator and the vents. Even then, you'd have to make sure the air stays in contact with the evaporator long enough to drop to your desired temperature. GMs standard for A/C temperature is 40F lower than outside air. Make that happen, and you'll be quite happy, I'd bet.
By the way, you could just override the compressor controls to find out what the system is capable of, instead of messing with resistors and expansion valves.
