Since they have already acquired three British colonies, the Spanish Government is certainly going to keep these three colonies in its hands.
The Spanish Colony should definitely also have a considerable number of Spaniards, because for the Spanish Government, Spanish immigrants are the basis for ruling the colony.
Of course, those Portuguese immigrants might also comply with Spain's rule. Compared to the colonialists of other European Countries, they have no trouble communicating with Spanish colonists, and their culture is relatively similar, making them clearly more akin.
Especially with the British Gold Coast, this land has quite a number of Portuguese people. If Portugal can be incorporated into Spain's colonial rule, Spain would be able to quickly control the situation in the British Gold Coast.
The three British colonies in West Africa are relatively scattered, but the distance between them is not really far.
