On the one hand, you have Napoleon's stated intentions, and on the other, what he might have actually had in mind. Here's the former, in a statement he drafted while exiled on St. Helena:

I went with confidence to England, with the intention of living there, or in America, in the most profound retirement, and taking the name of a colonel, killed at my side, resolved to remain a stranger to every political occurrence, of whatever nature it might be...

I am at any time prepared to retire into private life, and I reiterate, that when it shall be judged proper to discontinue this cruel place of Exile, I am willing to remain a stranger to politics, whatever events may occur in the world. This is my intention, and anything which may have been said to the contrary is incorrect.

As for his real plans, given his personality, what happened at Elba, and his state of mind at St. Helena, it's hard to believe he would have been content to live quietly in private life for long.

EDIT: Here's another quote—from Emil Ludwig's Napoleon—which sheds some light on the subject:

From that vantage ground [America] I should have been able to guard France against humiliation from abroad, reaction from within; the dread of my return would have sufficed. In America I should have established the center of a new French fatherland. Within a year, I should have had sixty thousand men grouped around me...It would have been a most natural place of refuge—a land of vast expanses where a man can live in freedom.

There is a very obscure and old book essays published in 1931, of which a Winston Churchill was a contributor, titled If It Had Happened Otherwise. One of the essays in it, by H.A.L Fisher, features Napoleon escaping to New York after Waterloo and eventually making his way to South America where he joined forces with Simon Bolivar. The essay is written from the perspective a New York scholar who became Napoleon's personal assistant. It's an interesting hypothetical that might be of help to you.

This one should of been listed on the "historical what if" sub but, that being said. I think a lot of things could of happened. Had England, Prussia, and Russia found out he was in the states they would of demanded his return or face them in war. The US didn't fair to well in the war of 1812 against Britain alone, they most likely wouldn't want to take on the whole alliance.

60,000 men. Where would he get the means to supply them? Where would he have gone with them and how would he have gotten them there? Obtain a small fleet to transport to one of the French colonies with the English Navy/Army in pursuit.

He would have to remain very obscure to get away with it.
