My reading of French History show that Napoleon never intended to make himself Emperor.
He was a loyal General of the Republic till the Republic collapsed. "I found the Crown of France laying in the Street, and I picked it up and placed it on My head"
I don't doubt that Napoleon could be a American Military hero, and rise to President like Jackson or Grant. But would He go the Military Route.
He gave consideration [otl] in his youth to the Religious Life.
Growing up in the US. Whe can get a Napoleon the Banker, The Farmer, The Sailor, or even Napoleon the Mountain Man. Accompanying Lewis and Clark, Or Carson and Pike.
