Unless you can match the variety of work and the net value received by the engineer, you can't. But you're not looking for the type of engineer that will succeed at consulting - these people will in general be more extroverted and will look at he risk/ROI as a life-calculus. You're looking for the less flamboyant and risk averse engineer.
