Not so nutty. Jet approaches final are quite flat, precise and predictable. You have the opportunity to try one after another aircraft, perhaps one every minute depending on separation.
Now the air would be quite turbulent and disturbed so putting a lightweight drone in the right spot at the right time would be challenging.
Our opinions differ.
Ducks and Geese get sucked into jet engine intakes all the time when they get into the flight path of a jet airliner ... so there is no reason that a small drone positioned into the path of such an aircraft would not also be sucked into the engines ... or hit a control surface on a wing or hit the windshield ... regardless it is quite feasible. And viewing the Jeppesen Flight Database to get altitude and vector information is quite possible - not heavily restricted as one might think.
