Far more complicated than that. The ventilated seats each have 2 motors (fans) inside them, controlled via the Heated Seat Module. The HSM sends variable analog voltages to control the fan speed. The wiring for this could be tricky, the wiring diagrams for the different seat configurations are quite complex, especially when they are heated/ventilated/power adjustment options/memory. In addition there is wiring for the front passenger seat bottom cushion contains which an Occupant Detection Sensor.
I'm sure it would be possible to wire the 12v seat fans to an aftermarket switch, but the challenge lies in getting the rest of the seat functions to work properly. One look at the seat wiring diagrams would cause most folks to not want to take the challenge.
It *might* be possible to just swap in the seat cushions themselves (and fans) but the wiring for the heating elements would probably be different (the vented seat pad and the heated seat pad are a one piece assembly).
