The French could definitely not take over the British colonies. British colonists outnumbered French colonists by a huge amount, something like 10 to 1. The strongest possible French victory would see the French keeping Canada and Louisiana and reducing British control in the west.

Then France would have to find some way to attract lots of settlers to its colony. In OTL it never found success doing this, outside the smallish zones in North America that still speak French today. (southern Louisiana and Quebec)  If there is not a huge influx of settlers, I think the 2 centers would drift apart after independence and the land between eventually taken over by Britain or by Anglo-American states. Honestly, to get the population high enough I think you need a POD that is earlier than the Seven Years War.
