I think at this current moment your ideas presented aren’t going to be put in soon because they’re already on the brink of releasing Christmas for 2017. With that being said, your two costumes recolored to being gold would definitely be a great addition to the game for St. Patrick’s event 2018. Possibly give them 15% reroll boost as well to compensate for the fact that if you wear them you wouldn’t be able to also wear the Lucky Lep hat.
