There's also the interesting question of how an averted French Invasion changes things in Russia, especially if replaced with an earlier Anglo-French Peace and end to the Continental System; OTL, these strains were the undoing of Alexander's liberal minister, Mikhail Speransky, and could be said to have set back liberalization and modernization in Russia by decades, so TTL could have some really interesting potential in that respect.
And actually, on the subject of Russia, what does this mean for the Ottoman Empire? Because the imminent threat of Napoleon's invasion was pretty much the crucial reason that the Russo-Turkish War ended in 1812 the way it did; even if Josephine doesn't send French troops (or coordinate Austrian troops) to help carve up the Porte's realms, the simple fact of Russia having more manuverability for their aggression could mean the annexation of Moldovia and Wallachia, or possibly even further Ottoman losses in Bosnia, Serbia, and Bulgaria. Thoughts?
