Sure we could. I flew the 35A yesterday morning, not long before I posted above; I flew the 77W the day before: The workload is higher in the 35A than in the 77W, 737/738 due to the lack of automation or system integration. The question is how much fun it would be single pilot in the sim. So handling it is less the question I raise than how much fun it would be with greater system depth and complexity, as none of that would be automated or integrated as in the modern airliners. And since fun is relative, YMMV, right?
