You can't even do things like 'give Germany the German focus tree,' because what happens to e.g. 'England' or 'Jerusalem' has managed to migrate into Italy and now also rules scattered counties in France and Russia. At least with CK2 to EU, you can associate cultures with NIs, and it doesn't matter if e.g. I wouldn't rule out a modder creating one at some point (a la the EU=>V2 ones), but I doubt Paradox will do an official converter ever again.Īnd as other people have noted, focus trees would be a nightmare to deal with, unless you give literally everyone a generic tree.
