RE: Is it possible?
It certainly could be done, but it will require modification. The easiest way I can think of to do it would be to attach a potentiometer to the steering wheel with a standard servo plug attached to it. The transmitter would have to be modified a little bit with a jack for the steering wheel plug and a switch to switch between the steering wheel and the transmitter steering wheel. If you are lucky the steering wheel already uses a potentiometer and if you are even luckier it is the right value potentiometer, in which case all you would have to do is tap a plug into the wiring. The gas and brake pedals might be tricky because they are separate pedals, I wouldnt know how to do it without a wiring diagram. I have an old N64 steering wheel/pedal set, Ill crack it open and see how it works if you want.
