Read a book! I got it! But setting the religious thingy aside for a moment, what do you guys think about my Scandinavian proposal?
I do like some of the proposals, like more provi in Norway and Sweden.
I like the idea of there being HRE incidents involving Denmark and Sweden, as both of those nations were big threats to the HRE and the Danish were even barred from HRE affairs in the Treaty of Lübeck. This could be an event in the HRE that could block Denmark from joining in the League War, but probably will have to be after Denmark already tried to expand into the empire. There could be an option to let them do what they want that would improve relations with Denmark, but make you lose some imperial authority.
Scandi should 100% be buffed, probably the worst formable, which is saying something when Sokoto exist.
I feel like the Kalmar Monarchy is an interesting concept, as the Kalmar Union had a hereditary monarchy, but also kinda an elective kingship. I feel like it is hard to implement the actual government debacle that happened there. I do feel like you had a good idea, but, not as well.
Personally, I feel like the Rigsrådet would be an interesting thing to try to implement, and can be under the Kalmar Monarchy title. Basically, what the Rigsrådet was was a council of noblemen and councilors for the king that represented their respective kingdom (there was three of them [for the three nations], and they had like 35-40 people each), and together, they would help the king rule, but they will also make regional laws for their land as well.
I feel like with the Kalmar Monarchy, it would work with the king being the head, but then every few years, the junior partners get to choose a council (Riksråd) to send, kinda like a colonial government in game, but the king has less power. They will get random stats when the "election" comes up to kinda show the mix of talents (like you could get a 6/2/3 Riksråd), and they will take the job as the primary "ruler" of your nation. You are still locked behind the restrictions of being a junior partner, but, there could be somethings that change due to the Riksråd. Maybe Improve Relations has a buff, and you don't need to spend prestige on stuff, and no hit to trade power. That is something I came up with on a whim, and I am unlikely to improve on it. If you like it, feel free to expand and improve it if you do.
I do not agree on the Denmark-Norway and Sweden-Norway formables, as I am gonna be honest, it wouldn't change much imo. Maybe Greenland could be formable in the way that Iceland is (requiring you to only be two provinces and of the right culture), and maybe the North Sea Empire, like I was spitballing earlier in here. I do not see DN and SN being formables, as unlike the large PLC, it isn't that big of a territorial change and can be a common occurence in this game. I used to advocate for Lobardy in the game, but, it would basically just be Mantua being annexed by Milan and that would be the end of it.
If there were to be more Norse/Scandi/Nordic formables, I would say these are the most likely canididates: Greenland (in 1444 it was owned by Norway but EU4 didn't give it to them), Danelaw, Finland, Anglo-Scandinavian Empire, Gael-Gall, and Langbarðaland. Finland is already releasable, so it being formable isn't too complicated to understand. Gael-Gall is a mix of culutres of the Celtics of Ireland and Scotland and the Nords, but it could be the name of the region if they were united. Langbarðaland is basically Nordic Naples, it was a colony made by the Nords when they fought the Emirate of Sicily and won, and they took all of the territories it owned and kept it as their own.
Those are just my thoughts on what you proposed however, so take them with as much salt as you want.
