What about adding a separate province for Åland? (Sweden)
It's quite silly & no doubt outright ridiculous to have it included with the mainland as is currently the case.

Also, some obvious areas desperate to geographical improvements would be Ireland, really the British Isles in the vanilla edition of the game is outright nonsensical, but in particular Ireland and Scotland needs some serious fixing (Isle of Man, why not add both Outer & Inner Hebrides?), the Balkans could for sure also use a touch, and the Iberian Peninsula feels incredibly stale, also a quick few google searches shows that there's historical inaccuracies there as well.

The Meiou & Taxes team did a fantastic, close to perfect job in all of these regions.
Perhaps you guys ought to have a look at how they solved these issues to add further quality to the regions?

There's also a few small but historically interesting islands still missing that could be added in Scandinavia to further improve gameplay and historical accuracy in the region.

I'm making a list of ideas for provinces to be included, that I think would improve upon the mod, if you're interested i'll upload it when I feel like i've gotten the most important provinces written down & hopefully you might include some of the ideas in a future update?

Cheers
