Interesting idea, next GB game I want to keep vassal dutch and scotland so i can feed them respective American CN, maybe even go so far as to federate Australia too.next game (probably next patch at the rate the first one is going) i'm going to try giving the canary islands to Asturias, to see if they will colonize the ivory coast for me. Basic idea is at diplotech 7, ~third war with castile, transfer occupation of Canaries to Asturias. Second war with Mali/Jolof, transfer occupation of Traza to Asturias. Should be in range to colonize the Ivory coast then in time for their 4th national idea. They should be able to core it at diplotech 7, and they get a free colonist as their 4th idea.
Issue would be giving france Canada Colonial land easily in a peace deal
The TC merchant for ivory coast i find easiest to getThey should pull trade into iberia, which is nice.... it always makes me mad how after I put forth the effort to subdue all of asia, france/britain can conjure up 10% trade power in the ivory coast for a sweet 60 florin payoff.
