When NASA was training pilots to fly the space shuttle to a landing I believe they modified the controls in a corporate jet to simulate the predicted response of the shuttle to control inputs. With today's technology I would think it would be possible to do the same with a small jet like a Citation Mustang and have it respond like whatever airliner you wanted. You could then allow line pilots to hand fly those. It would give crews actual hand flying time at a fraction of the cost of flying the actual airliners.
