Back in the days of the cable systems we did it quite frequently, especially on OMC engines. Just left the tiller handle on the engine, pushed up and connected the remotes with adapters to mounting points provided on the engine. Steering was a connection to a hole in the center of the tote handle. You could do the same with a Teleflex single cable. Deadman could mount to the transom with an after market bracket that marine retailer's sell. Same company might sell the cables and adapters for throttle and shifter too. You may have a tilt bracket tube cable assy that would fit your engine whereby the outer steering tube would mount to the starboard side of the tilt tube and the center would protrude out the Port side with an S bracket that connected to the front center of the engine.
Check Iboats for needed part. Check them for the control also, it's a Commander 2000 and get yours with a wiring connector that fits your engine if fitted with a remote connector. If not you would have to "cut and paste".
