A pacifist player is never a risk to other players unless he is attacked. In that case if the pacifist player engage in combat then he does take the risk of being killed and looted just like a pvp-player. With a combat timer he wouldn't be able to take advantage of his safe zone, so that would be a fair fight. I see absolutely no reason for that part of your suggestion and no advantages to anyone, its only a pointless limitation. Other parts are fine.
