Would need to be a very very long stick for the likes of oblivion, unless they just used outer seats. Can't see anyone coming at you with a hooked stick anyway. It's not possible to check restraints and belts properly unless up close and personal. The only way is they observe you checking the restraints yourself. Would that be acceptable though?
They do this at Disney a fair bit. For example asking you to push up your restraint as they walk past on RnRC or pull on a yellow toggle attached to a seat belt on the likes of Test Track and Star Tours so they visually check if you are secured in.
It would be technically possible for Towers to introduce similar measures, such as staff asking you to push up on coaster restraints and pull on seatbelts - whether Merlin H&S would allow it is another matter.
