It's possible, but difficult. The biggest difficulty is that the pulley and the air inlet are on opposite ends. On a rwd car, that puts the air inlet on the back of the engine, facing the firewall. You would probably have to fabricate a quick (and flattened) 180 degree turn, then mount the throttle body. The tb would have to be made steady somehow, and be connected to the throttle cable.
