No, the whole point of the long stem is to get his body as close as possible to the Derny. If he isn't going to be paced, the modifications confer no advantage; he could just ride something with a longer top tube if he needs the reach.
Of course, the correct approach would be to get a Stayer bike, because they are designed to handle well at high speed while getting the rider as close to the roller of the pacing moto as possible, but clearly we're not dealing with a logical fellow here.
