WI the norse took over france and britain, and did not immediatly become french or anglish or catholic
It'd be a very interesting situation, language-wise.
At the most conservative, France will have a Romance-language with a much higher degree of Norse borrowings. Verbs like 'river' (to tear apart; to rive, rove, riven in English) would pop up, and they could end up boiling Œuges instead of Œuf. At the most liberal, we could see French altered such that it would pronounce the ends of words like Spanish, have some form of dental-past-tense (ouvrir, ouvride, j'ave ouvrid), a more substantive 'to have' (j'ave, tu haves, il/elle ave, nous havons, vous havez, ils/ellles havent), and so on.
In England, with a more Norse France, it would possibly give us an English as inflected as Dutch is today and with far more Germanic root words, especially if William the Conquerer retains a Norse language amongst the elites and him and still tries to conquer them. If not, then there's be a dialect continuum between England and France similar to that of Dutch/Low Saxon today.
Ok the main problems are lack of population. Why dont we also give thema a MASSIVE population boost, so the number of migrating vikings outnumbers the native french. Slightly ASB
Actually a lot of the simplification of Old English seems to have started following the Danelaw rather than the Conquest.In England, with a more Norse France, it would possibly give us an English as inflected as Dutch is today and with far more Germanic root words, especially if William the Conquerer retains a Norse language amongst the elites and him and still tries to conquer them.

Wasn’t France originally Germanic/Frankish, but then got Romanized in early Medieval times?
No. Gaul was Romanized already when the Franks came into the scene. The Franks themselves were pseudo-Romanized, having lived in imperial lands for two centuries prior to the Merovingians dispatching Sygarius. In any case, the Normans would likely follow their Frankish predecessors.
Then where did French people get their NW European genetic admixture from?
They have a lot more of it than other Romance Speakers (Iberians and Italians. Romanians are genetically pretty similar to their neighbors, despite their Romance language)

IIRC, France's population was like a third of the whole of Europe at that time, so even then, I'm not sure it would be enough.If Rollo didn't settle for the lands in modern day Normandy and instead ousted Charles the Fat and made himself overlord of Paris, and France as a whole, could there be a massive influx of Norse settlers coming into France once they hear how fertile and wealthy the lands truly are? That's about the most likely scenario I can think of, and I think the chances would be much higher that Rollo's Norsemen simply assimilate before too long, except instead of just controlling Normandy, they also control much of the Seine through Paris, the Ilê-de-France, and possibly beyond.

Looking at the Cauchois dialect (the language spoken in the Pays de Caux, one of the areas of Normandy most heavily settled by the Nords), it's very similar to modern French and there's little word borrowing from Norse. In the event that Rollon somehow conquer most of France (which sounds dramatically unlikely), the situation would probably be similar. I expect Norse influence would be very thin.
