I also think there is a really cool opportunity here to allow people to compete and donate to history.

If you look at the last major restoration "Once the project was approved, Viollet-le-Duc made drawings and photographs of the existing decorative elements; then they were removed and a stream of sculptors began making new statues of saints, gargoyles, chimeras and other architectural elements in a workshop he established, working from his drawings and photographs of similar works in other cathedrals of the same period." "Other craftsmen made stained glass windows in Gothic grisaille patterns designed by Viollet-le-Duc to replace the destroyed medieval windows in the chapels of the ground floor of the nave of the cathedral." https://en.wikipedia.org/wiki/Eug%C3%A8ne_Viollet-le-Duc#Not...

Artists across France should be engaged to submit works with the promise that effort will be made to preserve them for centuries, if their work is chosen for inclusion. Even the stuff that doesnt make the cut could end up somewhere.
