I assure you, they will...

Well, besides the fact that a bt of 5-8 more can be a huge advantage in this area, the italian states seems just as blobbing as the HRE states, which in fact wasn't as possible as shown. The same goes for Venice, which is invaded by Austria in several games. A good player may be able to solve the problem diplomatically - but I'm sceptical if the AI is able to do that.
All in all, like the HRE members were eager to preserve their liberty, the italian states had the same goal in common. When a state in the area grew too strong, the others alliied suddenly against this menace. The whole system of the Italic league of the 15th century, which preserved the
status quo until the Italian Wars, isn't even in. Instead, nations as France, Austria and Aragon have some decisions/missions which lead to certain doom.
My considerations are the following:
- Overhaul of the Italian peninsula without destroying european balance (in this context, the big neigbours must get some advantages, too)
- Removing north italian provinces from the HRE
- Adding triggered modifiers, which determine the power status of an italian state on the peninsula by monthly income, provinces and vassals in this geographic area, giving a bonus to smaller, and a malus to bigger powers. If a power becomes too strong, the other states will unite in a coalition by event.
- Adding event-chain/decisions concerning the Italic league to provide a sub-system, which would make expanding in Italy (by italian states and foreigners) difficult
- Giving France the chance to claim Naples after Anjou/Provence doesn't exist anymore, and France holds these provinces; same case for Orleans and Milan. In that case, the league may break, and HRE/Aragorn gets the chance to intervene, starting the DHE of the Italian Wars.
- HRE has the chance to regain Northern Italy as HRE-lands, in a manner like Charles V had in mind
- Because of that, making Italy more interesting - more provinces, better bt for the boot - it would be more rewarding to follow this approach and Italy won't be unbalanced or overpowered, but a unique playground with new strategies and options (not only for Italian states, but also the neighbouring great powers)
