I'm afraid that would not be wise. It would take too many turns to move a settler by sea to ivory coast... probably more than it would take to move one by land.
I was never a huge fan of colonizing ivory coast anyway. It's very likely that the Americans/Aztecs/Germans/Greeks will get all the ivory before we'll even make it there.
