If something similar to Tangers or post-ww1 Fiume and Danzig, maybe, the united states initially just wanted free navigation on the Mississippi, but Napoleon was the one who offered the whole of Louisiana, not that Jefferson said no. Say, instead he offers the more inland parts and joint administration of New Orleans itself while keeping LA and AK (that would be impressive butterflying there)
If Louisiana territory is entirely part of the US, though, I'd say no, not remotely plausible.
