What if England was Germanic and France was Romance-speaking?

This is an idea that came to me as I continued with my **Victania** worldbuilding project, in which I imagine a world where the Roman Empire never fell. I know there are a lot of alternate history worldbuilding projects, with people imagining what if the Mongols had conquered all of Europe or Whatever, but this one happened to spark an interesting idea about linguistic diversity.<br><br>In my Victanian world, the Roman Empire still exists, but, because they never had to fight barbarian tribes, they never lost their provinces in Gaul to the Franks. Even further, the Franks eventually intermingled with the Gauls (through a process of assimilation called the *gaullisation*) and eventually adopted the Gallo-Romance language as their own. In this world, Germanic tribes like the Anglo-Saxons were eventually defeated and assimilated into Roman culture. The result is an England that speaks a Romance language and a France (or *Gaule*) that is notably Germanic.<br><br>This got me to thinking about what the linguistic landscape of the real world would be like if England had been Romance-speaking and France had been Germanic. **Romance-speaking England**: It's not that far-fetched - we could argue that the ancient Britons were already Romance-speaking, in a way, since the ancient Britons spoke the Brythonic language, which is in the same language family as Romance languages. The Roman's influence on southern England would have assuredly made the language more Romance-influenced, and it's likely that the Latin of Roman England would have evolved in a similar way to the Latin spoken in France, resulting in an Anglo-Romance language. I think it would be interesting if England, like France, had had a Romance language from the beginning, with the Anglo-Saxon invasions only influencing the language through loanwords, similar to how Old Norse influenced the English language.<br><br>**Germanic-speaking France**: Now this is where things get really interesting. Remember how the Franks were originally a Germanic tribe that conquered Gaul from the Romans? What if the Franks had imposed their language on the Gallic population? This would have resulted in a modern France that speaks a West Germanic language, comparable to Dutch or English. It would have also meant that there would be no Romance language spoken in modern-day France. Instead, the French would be a Germanic people who speak a Germanic language. This idea is also not too far-fetched, since the Frankish language did heavily influence the modern French language, and many common words in modern French are of Frankish origin, such as *bacon* (from Frankish *bakkon*, or "buttock of pork").
