"Strangely, even though the Bottle Street Gang and theHatters Gang are enemies, Slackjaw resembles some Hatters that are commonly seen in The Brigmore Witches, namely with his attire."

I can't provide a source on that, but Slackjaw's design was based on concept art of street thugs for Dishonored (you can see his model used in the cut version of Eminent Domain). The developers must have made him a full-fledge character after that and gave a different appearance to the Bottle Street thugs to differenciate them. Then they reused that same concept art for the Hatters in The Knife of Dunwall, and gave them their own unique face models in Brigmore Witches.
