What's wrong with the ref contacting a person responsible for a camera looking in on the goal line like Sky Sports or ITV do when these things occur, if it happens (and it does, it's not rare), if there is enough protest, he WTs the reply office, "Ello, was that over the line?". - A quick yes or no within 1 minute - Job done.
A 5th ref watching all the slo motion replays from the TV would do the job in 30 seconds and could then radio to the ref and it would keep the game moving. It would also help with all incidence and not just the goal line.
