I know when Darren Hardy of MGFnTFbitz had his Moonshine Monogram TF resprayed, the painter also sprayed his steering wheel with the Monogram paint too. It worked a treat and looks amazing. So its not just leather paint you can use. If you have any rattle cans and possibly lacquer too, may be worth trying them. If it does not work then should be easy enough to remove.
This is the only picture I have of it and its a cloudy day so the paint job does not stand out but you can make out the top of the steering wheel.

PS Found another taken at POL last year shows it up a bit better although my camera exposure was a bit wrong! He also painted the center console too.
