What is this?
How serious is it supposed to be?
What is the POD?
Generally, I don't like when people include alternate geography just for fun. Alternate geography would have a huge impact on history so it shouldn't be thrown in later on for the lulz. It's very interesting, but IMO its more of a TL of its own. BUT, if this map isn't meant to be too serious or is very soft AH, then that's a different matter and I think you should do what you think is cool. This is ofc all my personal opinion.
