Trying to do that with oak will be a challenge, because oak is a denser and stronger wood. Still, they used a single tree nearly 200 years old to produce those eight rafters. I think the Notre Dame is going to need a lot more and centuries old oak for its own roof.
At least only the rafters need wood like that, and only if the French don't want to replace the burned down wooden construction with something else. I'd advise using wood though; as long as the place doesn't get too damp wood doesn't rot away the way a steel construction would.
