/r/HistoricalWhatIf may be a better place to pose this question. This isn't my field of study but trust me, I get "what if" questions all the time and they are very frustrating to try and give thorough cited answers for because trying to explain hundreds of years of history that did not come close to happening is very, very difficult.
They tend to have a team of very competent people who (usually) what they're talking about + have the extra motivation to throw on some fanfiction flair on top of it.
Sorry, but your submission has been removed because we don't allow hypothetical questions. This sort of thing is better suited for /r/historicalwhatif.
