Suppose that the Sardinian army adopts a different strategy in the First Italian War of Independence: instead of trying to besiege and take the Austrian fortresses in the Quadrilateral directly (and, among other things, wasting a precious amount of time at the siege of Peschiera), they cross the Adige and fight Laval Nugent's army in Veneto before it can join forces with Radetzky in Verona (while leaving a detachment behind so he doesn't pull off any shenanigans), something that IOTL paved the way to a decisive Austrian victory at Custoza.
With its forces in Lombardy-Venetia either defeated or slowly starving in the Quadrilateral, Vienna is forced to hand over most (if not all) of its lands in Italy to the Piedmontese more than a decade earlier than IOTL (or almost two decades, in Veneto's case). How does this affect the unrest taking place elsewhere in the empire, particularly in Hungary? IOTL the Hungarians only declared independence in April 1819, could they do it earlier here? What about the uprisings in Prague and Vienna?
