I really like the direction you are taking this mod. However, I think the Bloby de jure map could probably be change and broken up. Some of these suggestion have already been stated, however, I think a better explanation is in order.
1) Bust up k_spain into various smaller kingdoms. I fear that the Spanish peninsula will just become a place nobody looks at because it will constantly be divided between Portugal and Spain. Even if Catalunya breaks free, its de sure is too small to actually make a difference against Spain. I suggest you give d_aragon to Catalunya so if they do break free, the Catalans can actually resist Spain. I also suggest you create k_navarra between France and Spain. The basques have kept their language and culture under spain and have a high level of autonomy within Spain proper. This also helps bust up Spain.
2) Alsace-Lorraine goes to France. I understand this region has been disputed up until WWII, however, France as it stands just looks too weak. Preferably, there would be some way to have Germany and France constantly fight de jure wars over this region, perhaps by busting up the duchy into alsace and lorraine, with one de jure Germany, and one de jure France. But, I would prefer it under France, since France has held the land since 1945.
3)Bust up german poland. I actually like the de jure setup over here, however, I think Germany has to many de jure claims. I would do two things to the setup over here. One, I would divide Silesia into two duchies based around to treaty of Versailles borders. Upper Silesia would be de jure germany and Lower Silesia would be de jure Poland. Two, I would create a new kingdom out of East Prussia. It just looks weird to have germany claim land that lacks a direst border with their land. I would create a new kingdom and put it in the Baltic Empire group.
4)Kurdistan. Not many people have discussed the middle east yet, because of all the conflicts over there. However, the Kurds are a people without borders that occupy a significant amount of land. I would take some of eastern Turkey, a duchy from Iraq and Iran, and maybe a province from Syria and create k_kurdistan. this will help bust up Turkey, which you were complaining about.
5)This one is minor. I really don't like the Kingdom setup in Italy, because it looks to much like 1870. Instead I suggest a different layout. There would be 3-4 kingdoms, each based around the much more recent north-south economic spit in Italy. They would be k_sardinia-peidmont, k_padania, and k_sicily, which could be broken into k_sicily and k_naples. This first two are in the north. Sardinia-Piedmont occupy all of its current land, simple because I see no other way to stick Sardinia in a Kingdom. Padania would occupy all the north until Rome. The Naples/Sicily setup is a obvious division of the south.
6)Scandinavia. People have discussed the kingdom and empire setup here, so I offer a different way to break up the blobs. Create the k_skane that someone earlier suggested, because the people there have always been a mixture of Swedish and Danish. I would leave e_skandinavia intact, however I would also add the e_sweden titular empire if people want to forge the Empire of Gustavus Adolphus.
7)Change the Imperial Setup of the East. Currently Russia is just way to bloby, and looks poised to seize the East. What I suggest is a rather large change. First, k_belarus, and k_ukraine be moved under the polish empire, which would be renamed to poland-lithuania. This is because, from the pictures you posted, I appear poland is getting the short end of the stick, and this is to compensate for it. Poland-Lithuania would only be formable if you hold the lithuania title as well as 80% of the de sure, similar to Abyssinia from vanilla. Russia would be broken up according to the map posted earlier, and made a empire from day one. Note that I left crimea under russia, to reflect the current disputes in the region. This should help break up the blobs in the east.
8)Divide India. Similar to the Russian proposal, India would become a empire from day one. Each of its current government districts would become kingdom level, to help balance the region, and reflect the cultural divides present in the region. I haven't thought much about this one, so sorry if it lacks a good argument.
9) Idea, not suggestion. Perhaps turkey, bulagria and greece could become a single empire in the balkans, to reflect the various states there. Its name and flag could change with cultures and religions to reflect whoever rules the region. A greek might see the byzantine flag with a byzantine name, while a turk would get Turkish Empire flying a turkish flag. This one is just a idea.
