That would be self-defeating. You'd be introducing hot air and
moisture into the air which would then have to be removed by the A/C

Hot air? How does an evaporative unit add hot air to a room?

By sucking it in from outside. A/C units recycle interior air while
dehumidifying and cooling it. Swamp coolers suck in outside air and
pass it over water (humidifying it) in an attempt to cool it.

Oh, I see. All of the evaporative units that I've seen use the air from
inside the building just like a normal AC does.
