The problem you are trying to solve is not the elevator operator. The elevator operator is a byproduct of a rushed cheap solution to the problem of crime/access to top floor/whatever the actual problem is. Therefore yes, a retrofit could be a potential solution among many others, what actually is the problem, and how effectively does the role solve it? I should step away from the elevator example because people are clinging to it a bit too firmly when the entire point is to question [job role], not the specific elevator operator.
