Well, to the right you'll see a map I did a little while back without any Americas. This sort-of illustrates just how freakin' massive the new ocean is. You should be able to see the effects of the erosion too (though looking at it again, we might be more likely to end up with a narrow protruding Brittany and a Bay of Biscay carved all the way back to around the Massif Central). Other places have erosion shown too, such as Papau New Guinea, Australia, Africa, and New Zealand. Spain is another place that would in retrospect look a little different: Galicia has quite erosion-resistant rocks so would probably end up sticking out more.
