Currently the states South Tyrol and Friuli are extremely small, practically to the point of uselessness. They exist in vanilla to create more granular historical borders in case of war between Austria and Italy, but due to the additions of HPM regarding core distribution in wars, they are essentially rendered moot.
In my own games I've modded the regions.txt file to merge Friuli into Istria and South Tyrol into Tyrol with no severe negative economic impact. The states are now better balanced and more able to create wealth due to being of a larger size. They do not become game-breakingly large--indeed, they are still on the smaller end of states--and as far as I can tell there are not any major issues related to core distribution in Tyrol or Istria.
Furthermore, this division would be more historical and better reflects the administrative divisions as they really existed within Austria-Hungary and interwar Italy.
Apologies if you have already considered this and decided not to do so for whatever reason.
