I love your first three ideas. I'm not sure how I feel about hat and doll trading, though. How are the big gang leaders and other people different? You mentioned that one of your ideas was that player-given dolls can't be traded. Aren't big gang leaders players? Lol.. It'll be pretty hard to go over every hat and doll and determine if they should be tradable. I like your thinking though. These should be looked into.
