western rome has a few minor issues:
1. its cores Portuguese colonies
2. it gives no claims on england once formed

Makhnovia, the ideology could be Non-Aligned or Communist.

United Anglosphere

The Spanish Empire:Mexico, Panama, Guatemala, El Salvador, Costa Rica, Columbia, Venezuela, Peru, Bolivia, Paraguay, Argentina, and Chile.

Can you please do Poland-Romania from the Barbarossa DLC. i think it would be a fun country to play as

Greater Mongolia with the decisions of creating the Empire aka incorporate inner Mongolia, western china, eastern china (Japanese puppet territories with inner Mongolia and Manchuria along with most of mainland china), subdue the middle east (once taking china you can get war goals), then the golden horde and the ability to create the Kievan Rus' as a puppet

The Saharan Empire (All countries in the sahara desert Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia)

East African union (ethiopia. somalia, Djbouti, eritrea and kenya)

Balkan Empire (all balkan countries+turkey)

Mesopotamia (i dont know which countries to put here so i guess you could do like iraq and syria maybe)

Bulgaro-Romanian Union

United Kingdoms of Sweden and Norway or Sweden–Norway
- Cores all Swedish and Norwegian territory
https://en.wikipedia.org/wiki/Union_between_Sweden_and_Norway

United Kingdom of Sweden and Norway

Idea: Swedish empire

Sweden, Norway, Lapland, Iceland, Estonia, Latvia, Denmark, Northern Germany, Northern Poland, Mauritania, Namibia, Cameroon, Gabon, The Indonesian Island of New Guinea.

Assyria, Start as Iraq, need Kuwait, Syria, Israel, Jordan, and Egypt. Very hard because you need to fight French and Britain

Some sort of CANZUK Formable, I can only brainstorm a Few Ideas for the name Because all these nations have majority populations for the British Isles. Can't be Imperial Federation because Britain can Already form that.

Idea: Britain can Form this and has to own all Canadian Cores, All Australian Cores, And All New Zealand cores. Gives you cores on all British White Settler Nations. Basically it just Gives you cores on all areas that are Majority Ethnically British/Irish another great addon for this after you formed the nation is that it could give you a decision to get cores in British and Irish Ethnic Areas in America, for a more Balanced core system this idea would work well, It could give Britain Cores on Alaska, New England, Seattle, Oregon, And some other Majority Ethnic British/Irish Areas. If you want you could even just Give every american core to britain

Names for the Formable nation that Britain, can form can include

Britannic/Britannia name
Non Aligned: Kingdom of Britannia
Fascist: Britannic Empire
Democratic United Provinces of Britannia
Communist: Union of Britannia

Flag Would Either Remain as a Union Jack because that already Represents the British
But some other Good Ideas would be a Flag Similar to the one for Canada from Kaiserredux but Instead of the Canadian Coat of Arms it would give you a Circular Think in the middle of the flag Either with a British Lion for Non Aligned and Democratic, For Fascist it would give you the thunderbolt thing from the British Fascist Movement and for Communist it would give you the Communist Hammer and Sickle
