If it is to be given only to select players, (which I'm very much against tbh) it could be done quite easily. Instead of a new ID or a mountable item, a much easier solution. Give them low level admin powers.
For example '.setadmin playername superadmin' gives them ALL the admin powers, which is what [Admin]s have. I'm not sure, but I'm thinking a new class could be made '.setadmin playername police' which gives them clearance to use this command.
Or before it's made public knowledge, the command could just be told to select people, either official faction leaders or dev team testers, but after all the necessary trial periods, I'm for the idea of this feature being open to all players.
