I'll very likely stick to some of the themes that exist with Britain already and tinker with a few things instead of completely uproot everything. If only for the sake of maintaining a very basic sense of continuity.

Once I have everything mapped out I'll throw a sheet up.

As your friendly neighbourhood Britbong, I'd like to request you make a solid decision about the state of Ireland in the UK in your sheet. If it's still in the UK (I think it kind of is), some kind of war (civil or otherwise) had to be won by the British/Unionists or some concessions given by the British to Dublin. By the end of the First World War IRL, the Irish were about ready to fight to the death for independence, where as 10 years before they were happy with Home Rule. I can't imagine how rebellious they were after 11 years of war. Maybe they could of broken off (unrecognised by the international community) for a few years after the war when Britain was at its weakest and were then re-conquered by the British during the 50's as a start to their new Empire building. 

Familiarise yourself with this song and you should be grand:
