In OTL, this was an all-Mexico movement that obviously did not come to pass. This site already discussed what the domestic issues would be like.
My question is, how would the foreign powers deal with this? The United States now controls the entire Gulf of Mexico and there is no southern neighbor they can arm that can fight the U.S. should the need arise. Would Britain and France declare a protectorate over Central and South America to prevent further expansion?
