You're overstating the tech held by the Confederates on one hand, and vastly underestimating the number of calvary -and artillery - for both.

Confederate weapons were not nearly as modern as you'd think, and their artillery a lot better than Napoleon's, as well. Nor would there have been any militia at all by that time.

Lee would likely win - most of his men would still have weapons that had a better range - but Napoleon would still give him a scare, I'm sure.
