Could it be possible to make kind of spin-off of this mod where you can puppet the USA ?
Kinda like in The Man in the High Castle

I was thinking about that, but there are plenty of The Man in the High Castle mods. Never tried them though. If they don't fit your idea, I'll see into it and proably make a spin-off mod or incorporate american puppts in this one.

I might go further and say that you could do it for the entire American continent !
Basically, if the player´s desire for expansion reached South America, you could split the land with Japan (the Pacific coast down until Chile) and the Atlantic coast up until Colombia.
Then you would have a "choice". Perhaps similar to the Vienna Awards focuses, where you could give the former colonies to their former colonists, for example, Brazil and Uruguay would be given to Portugal and Argentina, Bolivia, Paraguay and Chile to Spain as a sign of friendship... or something.
In case they refuse (I would suggest Brazil and Argentina refusing as the AI´s prefered path), the player would get a war goal against them.
Due to the fact that South America is a difficult place to wage war in, it would be an interesting and surely challenging end game conflict.

This is probably a really difficult thing to add in I presume, and I would say it should, in case you agree, a very low priority on the to-do list.

This is interesting. The problem is I don't really familiar with Latin America of the time, so it would require research. And a lot of imagination while Japanese and German partition of USSR was planned on paper in one form or another. But I'll definitely look into this.

Could you make a version of the mod that doesn't add new states, for max compatibility?

I had the idea back in my mind because it has becoem an issue. Will do in the near future.

It is done. Here

Ah, thank you very much.

Make it work with focus tree mods.

The only focus tree that is affected is the Soviet one. It seems that could be avoidable in the next patch\DLC, so we'll have to wait.

this mod ought to include the final version of Generalplan Ost that removed kazikstan entirely and had RM Moskowen reach the urals but not beyond

basicly the reich took the land to the Europe Asia border

Perhaps different variations will be added with the new Decisions system in the new patch.

Could minor things such as the Lokot Autonomy, and What if RKs such as Novgorod be added?
Also special national spirits and leaders (for example, assigning a General to rule over an RK) would be great for the RKs.

While such things as minor colloborationist regimes and other what if reichskommissariats whould be interesting, I think they would bloat the game up. Additionally, I try to be close as much close to historical plans as possible. Japan did roughly planned division of Russian Far East and Siberia, hence these territories recieved Reichskommissariat counterparts, while no such thing as RK Novgorod was even planned, as far as I know.
As for spirits and leaders — may be. May be there will be a generic RK focus tree. The ides of assignigng generals as Reichskommisars is really interesting, though. Will look into it, much appreciated.

the nazis never intended to go beyond the Urals can you make an even to reflect this?
