If you are driving in hot/dry ambient environment, then perhaps its feasible to have a lesser impact, but still the theory is wrong. You will not gain any performance from feeding air conditioned air into an intake when the very air conditioned air you are feeding it is made by the energy from the engine.
My environ is hot/wet. Much of the energy lost in cooling the air is lost from condensation of water from the A/C coil. In a high humidity environment much of the energy is lost due to external condensation of the A/C coils and its sloughing off of condensed cooled water. This is an inherent inefficiency of all common vehicle cooling systems.
In a dry/hot environment, the water from the coils are dispersed via ambient latent energy in the air much more readily.
Also, I don't need my engine sucking my cool/dry air from the cabin either! Us humans need cool air as much or more than the engine does! At least where I live ...
