Like how France has the European parliament in addition to its national one? Yes, that may be true. Also I believe the Gristol Parliament would only deal in the island's businesses, since it is mainly ruled by the nobility of Dunwall.

EDIT: btw I'm not implying that the European Union is an empire. :D But since it doesn't seem like the Kaldwin had much authority on the other islands, it was more like an union rather than something like the British empire.
