I’m not talking about reinterpretation, I’m talking about faithful recreation. Archaeologists do that kind of thing, and it’s valuable, why not art historians?

And judging by your reaction my suggestion indeed is the right kind of transgression to recreate the thing.

If you want it a bit more pedestrian, just in case you happen to be a museum director: Ask the janitor to go into a hardware store, and buy a urinal they like. Then tell them to write “The real Duchamp” on it, and position it on a pedestal. Attach a standard museum plaque, crediting the work to the janitor.
