This is for the semi-cannon TL. I don't care what you want for your TL, but that's where I will help too.
The semi-cannon TL is just more on a "realistic version of the ASBish cannon TL". So we want to make things realistic.
That's for your TL. Where did your TL will separate from the semi-cannon TL again? In what year? It's around the time of the Mongols right?
If you will make the Ottomans annex Japan? What will happen to the scenario of Lulu in Japan fighting against the Britannians? Or I guess, this is for your own TL.
And I like the ideas. They could be put into the semi-cannon TL too, except for the Ottoman Japan thing. We need to keep a sakuradite rich mercantilistic greedy Japanese Empire around for Britannia to invade (for Brussels secretly).
Britannian Orthodox people? They would be severely persecuted by the Anglican government there. We need to give them an AMERICAN COLONY!
Wait. There is an existing Byzantine Empire and yet there are Ottomans too?? But in Southeast Asia??
Interesting. Interesting.
