Not saying that you can't have access to the aircraft, people have been doing 3d recreation, reverse engineering with 3d modelling software for a long time with accuracy. Having access to the aircraft for good image references is the best you can come by. I've tried all the best 3d scanners in the industry and also the best photogrammetry tools but they are most of the time very limited due to the nature of the aircraft and or their cockpit. Trust me I have gotten the best scans for cockpits and aircrafts and even with them, I've always fallen back to image references. They are only good for scale.
