To take the Louisiana Territory while Napoleon was busy in Europe. Maybe not 1812, but Manifest Destiny and a French blockade to that would eventually result in a clash of arms at some point.
It's not clear to me whether manifest destiny would have played out the same way without the Louisiana purchase, but I'm also not that strong on US history from 1803-1812.
I think the two scenarios I laid out for no Louisiana purchase might have been very different from the POV of what the French would have been doing in N. America. If it fails due to US politics, Napoleon probably still isn't going to commit much to maintaining a presence on our continent. But if the French reestablished control over Haiti, their interest in staying might have been greater, in part because of the colonial income from sugar and in part from having a base to force the Royal Navy to maintain a greater presence on our side of the Atlantic.
The French attempt to retake Haiti took place at a high point for Napoleon with the Brits pretty isolated after the defeat of the Allies at Austerlitz.

Little more than 7,000 to 8,000 of the 31,000 soldiers sent to Saint-Domingue survived and over 20 French generals died. On 1 January 1804 Dessalines proclaimed the colony of Saint-Domingue to be the second independent state in the Americas, under the name of Haiti, and was first made governor general for life before (on 6 October 1804) being crowned emperor as Jacques I. He massacred the last French colonists left on Haiti at the 1804 Haiti Massacre and followed a "caporalisme agraire" or serfdom system that did not include slavery per se but was still aimed at maintaining sugar industry profits by force.
The survivors from that defeat were comparable in number in the US Army at the start of the War of 1812. There were an order of magnitude more US men at arms in the militias, but would they have mobilized to fight an expansionist war vs a European power? I'm guessing that it would depend on how close to home things were happening. In the Canadian front during the war of 1812 there were `3X the number of NY Militia as US regulars in the
Battle of Queenston Heights. The quality of the US Militia was questionable at best in the war of 1812.
There might have also been some interesting US domestic political issues wrt fighting France vs Britain, especially if the French had reestablished slavery in Haiti.
