I had a random thought today in class, while there are a plethora of Saxony, Prussia, and Austria unite Germany threads, could Hanover perhaps have filled this role in some way?
I'm not sure of the legal and political practicalities, but perhaps if the George's saw Britain's power as a way to increase Hanover's status? Could it be done with the British monarchs at all, even if Victoria is butterflied away?
Maybe Hanover creates a nice little Germanic state for itself in the NW corner of OTL Germany, perhaps with Oldenburg, Westphalia, and some Rhine territory?
What are yalls thoughts on a Hanoverian Germany?
