Possibly just have things work on a province level, rather than state level? As in, no wargoals for states at all, but rather directly aimed at provinces?I would like to see a variance on war aims - for example let's say Italy has both Sicily and Malta, this makes up the state called 'Sicily'. As Britain I should be able to say I want to take it all, take just Malta, or take Malta and work for an independent Sicily. I know you could say make Malta its own state, but that makes it impossible to have the "take it all" option.
Basically, you should be able to choose to annex just a province or two of a state and not the whole state, and of course get less infamy for choosing that aim
