sniper protect mode?

was thinkin of a sniper mode, were it starts out like a pistol match and one sniper rifle on the ground, the designated sniper has to hit the other teams target if he dies the rifle is dropped and the who ever is left alive can pick it up to shoot at the target, the rest of the team covers the sniper, the most hits at the end of the time limit or once the other team is dead wins. sounds pretty fun on a good map just for it, were the snipers cant hit each other. dont know if starting with just pistols will be the way to go but sounds easier for picking up the sniper rifle
