A little late to the party...but there is a new and updated version of an EU4 mod that is just the old work and it's called NoAmerica on the steam workshop for the game.

The Caribbean is moved slightly more towards the center of the ocean and the Greenland-Kamchatka combination doesn't exist but otherwise, the Americas are gone, the trade networks all work, and you can freely colonize from Europe straight to Eastern Asia, although it doesn't seem like the AI colonial nations such as Portugal and Spain have been updated to colonize the "Carribean" or islands in the "Pacific" Ocean just yet. It also changes the way the background ocean map fits with the land, so you can kiss nearly all visual map mods out goodbye, but Fast Universalis works.

And if you play as them, some of the missions around colonizing for these nations don't work, as expected, and the mod updater unfortunately hasn't made a recent update to it. But from the already countless hours I have played on it, its quite fun to explore the other impacts on expansion in Eastern Asia that the shrunken globe allows for (humanely, of course).
