Your proposed way forward makes sense to me, PhilipG and I would expect that to be a step on the way there, again to prove the concept and iron out wrinkles. You probably don't even need the deck markings as long as the pilot can land it consistently in the right place and the Wizards can measure the landing roll for various weights and conditions. They might even do more "hard sums".
At some point, of course, you have to try it on the actual ship to see how it copes with other factors like a moving deck, anomalies like wind-flow around structures, visual effects or proximity to other equipment, etc. That's what test pilots are for once the ships are built
.
Presumably all part of the testing and work-up.
