Would there be a reasonable Point of Divergence for that? I am not sure that Austria would allow Tuscany to be annexed or vassalized by anyone...

France supported the pope and Sardinia a war would definitely break out or a proxy war would definitely brake out Unless either the congress of Vienna let the pope have more land a possible way to counter Sicily the good and old balance of powers shenanigans another dumb way that can happen is if the Austrians could let the papal states rule Tuscany is if they really weren't caring at the moment the way that works is if the Hungarians were throwing a party again but that happened in 1848 so most likely it happened earlier, and Tuscany was annexed.

Albeit i must remember that the leadership of Austria Definitely wouldn't be happy because the french sphere of influence would be larger in italy
