How about making capturing pigs the same mechanic as the Game of Crowns - if you see someone has a pig you could resteal it from them if you also have pig bait.
It looks like this was implemented (the visual cue, at least).
Was in the Double Rainbow party yesterday and one person had a mini piggy bait over their head while another had a mini hogtied piggy. They said it was "leftovers" from the Hogtied race or something.
