Some Ideas:
The JSF and F-22 would be nonexistent, unless built be PRoM, Texas, or PRoA.
The latest russian stuff would be in (SU-47, Black Eagle Tank, etc..)
Most countrys should get korean war stuff (Atom Bomb, F-86, F9F Panther, etc..)
Russians would export T-90 and T-80 tanks that they would replace with Black Eagle Tanks.
Seoul could be USA-Owned.
PRoM and PRoA should start with 1 B-2 Bomber, if it dies, it is gone forever, no rebuilding.
Each American Faction should get 1 F-117 each, if it dies, no rebuilding it.
F-16s, F/A-18s, F-15s, and F-14s should be almost PRoA and PRoM only, USA and Texas should get the F9F Panther, F-86 Sabre, P-80 Starfighter, Thunderjet, and F-4 Phantom II as their fighter and fighter/bomber arsenal.
United States of Europe and UK should have an arsenal of Leopard I tanks.
The Leopard II should have been discarded to make way for the T-90 and Black Eagle Tank.
Pretty much all nations should have 1 Atom Bomb that works like a Tactical nuke. Later they can build more, plus they could build Tactical nukes and ICBMs.
China could have a hydrogen bomb like they have in RL.
