If they became limited drops (especially in maps that aren't played that much), I'd be down for any of the above items dropping (maybe as a secondary drop to make it "easier" on the loot tables?). But, if it was just something you can get in the store, it might not be as "fun". If it's in the store, people will just buy it and go back to lurking. If it's a random drop, it'll bring back people to play.
