I just tried out your mod, first as Italy to 1938 and then as Germany to 1939. I must say this is the first time that I liked my HoI experience. I particularly want to see the effects of New Order events. However, after looking over the event files, I want to add a few suggestions of my own 
.
New Order Events expansion suggestions:
Ahistorical options marked with *
Cherkessia- created upon occupation. Choice whether to return to national Russia.
Turkestan- created either through occupation, revolt from USSR during civil war or agreement with Russia. If created through occupation, return to national Russia unconditionally.
Croatia- created upon destruction of Yugoslavia.
Serb National State- created upon destruction of Yugoslavia.
Bosnia- created with agreement from Croatia only.
India- revolt if Baghdad is controlled by Axis forces or the owner (Iraq) is aligned with the Axis. No revolt if Britain is Axis. Also revolt if Japan advances beyond Burma into India.
Tatarstan- created through occupation or revolt from USSR. Annexed back into national Russia upon winning the civil war.
Swedish-Norwegian protectorate* - Norway occupied or annexed, Sweden in Axis. Norway goes to Sweden.
Quisling's Norway- feasible for creation if Norway is under German control.
Danish Protectorate- same conditions...Iceland to US with option to install independent government, Greenland to US.
Cossack states (at the very least Don Cossack state...if created but re-annexed...Italian
Cossack republic...I am not sure on the historicity of the latter tho)- created through direct occupation or through revolt from USSR. Returned to Russia optionally as puppet state(s).
Bohemian-Moravian Protectorate (independent...Bohemian National State?)- eligible for creation of Czechoslovakia was annexed into the Reich. If created, gains Czech provinces only (no Slovakia or Sudeten).
Vallonia-Luxemburg- created through an event offering Germans to attempt to give Flanders all of Belgium or to separate Flanders and Vallonia (I'd use a separate tag for this one instead of Belgian one...I think you got plenty free tags anyway). Luxemburg's status shouldn't be taken into account...it would cave in to diplomatic pressure even without occupation.
While some of the "historical" ones mentioned here weren't actually implemented, it was entirely feasible that they could be. Germans tried to foment national-socialist collaboration in Luxemburg and used Bosnian, Tatar and Turkestani troops. They also proclaimed Indian provisional national government in Berlin in 1942.
Also a little note on these. Some governments mentioned here should be eligible for creation without England having to submit, obviously (Croatia, Bosnia, etc.). The ones in west/north Europe and Bohemia would presumably be kept under tight German control until British threat was removed.
On tags- all of these should probably use new tags (so they would have different flags and to facilitate possible allied liberation of the "original" countries) except for Norway and Denmark perhaps. Although, quite frankly, given the number of spare Central Asian and Far Eastern tags, one can simply give new tags to all of them.
Anyway, great mod.
