Yes!... except that if we let medieval French people have their say, they would raze everything to the ground and build something entirely new. That's what they did in the 11th century; the previous cathedral was at least 700 years old and they destroyed it without blinking.

For better or worse, we have developed a fondness for past artifacts that they totally lacked; it may make sense to build something modern on top of the old structure, but we need to save what can be saved.
