I think it should be the highest outlier of your physical stats and you shouldn't get a choice in it. If you have average charisma and huge strength then it should list you as intimidating, but if you are repulsive you shouldn't have a choice of hiding that behind your strength. In real life you don't get to choose how you look to other people unless you improve the way you look, which is equivalent to increasing your charisma in the game.
Perhaps if you're average on all physical accounts it could replace 'tall' for instance with 'corporate' if you're wearing a suit and I think that would be fine, but can only be changed with an IC item, not a command.
