I'm thinking of starting a TL where Napoleon manages to defeat Great Britain, resulting in a hegemonic and long-lasting French Empire (inspired by Zach's renowned Napoleonic TL).
Anyway, how plausible is this?: Marie-Louise dies sometime before 1820, and Napoleon marries Princess Charlotte of Wales, who would've been Queen had she not died in 1817. The English people and the House of Hannover would detest such a union, so what would the consequences be if Napoleon decides to force his will upon them? He would become the most powerful man in the world, master of continental Europe and now Prince Consort of England (the UK will split in my TL). If that marriage is plausible enough that I can write it, I also had the idea of marrying Napoleon II to Victoria, OTL's Queen Victoria. Napoleon II's half-brother would be King of England and its colonies. Thoughts? Too ASB?
