Good changes, these are far better than the ones we have currently. Some points:
German infantry:
G43 + assgrens seems a bit over the top. With the current muni cost of agrens I don't think they will be that popular. Maybe remove G43 and give camo. (This also makes sense since it's a ToW doctrine and G43 are, well, from 1943)
Storm
The revised Storm is still a very weird combination of abilities, slightly better than the current one I would say but I find them all sub-par abilities. Most of the stuff doesn't sound very "storm" - like

. It's more a stealth one instead of storm.
Blitzkrieg
Redistribute resources, why didn't you add this to the blitzkrieg one?
Seems like the perfect doctrine for it. I would get rid of the stug then.
NKVD
Partisans would be perfect for this doctrine instead of FHQ, I would give FHQ to the next commander:
Conscript support
Add FHQ and remove one of the abilities. I don't know which one though. Maybe for mother russia and give it a not listed doctrine.
