Assuming that Normandy has been divided between Brittany and Flanders (perhaps under Norman dynasties) could either of them do the equivalent of the Norman Invasion of England?

Naturally, either the Count of Flanders or the Duke of Brittany would need to have a claim on the English throne to start with. And even then, they would need Papal approval to invade another Christian realm. Stigand, the English Archbishop of Canterbury before the Norman Conquest, had gained his position by royal appointment rather than Church practice and was known for other ecclesiastical abuses. Because of the Pope's blessing, and the promise of land in England, the OTL Duke of Normandy was able to bolster his invasion force with knights and soldiers from across France, not just from his own native duchy.

Some interesting comments.
Looks like the consensus is with the "Duchy of Flanders" being more likely to attempt and achieve a Conquest.
Assuming that is the case could the Anglo-Flemish secure the independence of Flanders from France? Would it be included as part of the Kingdom of England?
