This is probably a good idea, using testers closer to your target audience should improve results a degree. However, I think this is kind of missing the point.

Wasn't the problem with the MCAS system on the max that the system was added to the airframe without re-qualification required? Shouldn't the solution address how Boeing and the FAA qualify aircraft for qualifications, not how the aircraft itself was tested?
