I would love to see a Crossover Cosmetic set added to the Pirate Emporium that pays homage to Connor Kenway from Ubisofts AC4 Black Flag game.

We already have crossover cosmetics from Xbox's IP its time we got one from a 3rd party and this is the perfect one to start with.
Here is his outfit from that game:
