I've been wondering about a timeline where the ARW was averted, and some sort of appropriate governing structure is set up that's suitable for both sides, and the empire is kept together until the modern day.
In this situation, would people from America be interested in settling in other parts of the empire, such as Kenya, Rhodesia etc? Would it have the same appeal to them in the way it did to many Britons? Does it offer them the frontier in the US doesn't?
