Disagree entirely. Your suggestion is overcomplicated as it adds in even greater numbers of sterile eyes.

The decision needs to be made by the on field official.

They have the flow and the tempo of the game, they know if something has been bubbling under.

Three remote 'judges' sitting with a buzzer Infront of them is farcical.

Challenge.
Review the incident.
Stick or overturn original call with zero outside interference.
Crack on with the game.
