That's something I didn't consider, the literature of the colony. I imagined that due to the large production of cod, wood and grain the colony would have an elite that while not as rich as the Brazilian would be rich enough to send their children to universities.Additionally, in colonial Brazil there was a wealthy elite that was able to educate its children at the University of Coimbra. A Portuguese North America likely resembles French North America with most settlers being comfortable, but illiterate with little specie to trade to send their children abroad to learn. If a rebellion does occur it might be more similar to the peasant revolts of Europe.
I think that the most likely to happen with a colony in the amazon, now in South Africa they have a better chance of working.. William Courteen Jr. also chose Madagascar was also the site of an early Puritan colony as it too was seen to offer great potential, sending 145 men women and children to Saint-Augustin Bay in 1644, hoping to replicate the success of Virginia, however starvation and disease led to its abandonment in 1646. A second attempt to establish a Puritan colony on Assada (Nosy Be) in 1650 was abandoned within a few months, for much the same reasons.
