On the other hand DJI has flown their regular consumer Mavic 3 Pro(although I bet it has been modified in some way) all the way to the top, so I have no doubt that with enough of them you could construct almost anything. Not that it would be allowed or even desirable by anyone there.
The helicopter flight that landed on the summit briefly was helped by some strong updrafts according to the pilot. It also looks like it was a number of flights.
