If I was capt and my relief FO was drunk, I'd keep him in his seat/bunk for the flight, and resolve the issue the old-fashioned way (out of sight of CCTV) on arrival at the hotel.
In the US at least you would face the loss of your certificate for knowingly allowing a required crew member to work intoxicated. Covering for a crew member in the manner suggested merely insures he will fly again intoxicated. The proper way to handle it would be to have the pilot exit the aircraft and be replaced. From there he would be required to enter a alcohol treatment program. ALPA has a very successful program with a near 100% return to work rate.
