Alternate History Game Mode - Choose Your Doctrine HWW

So I was listening to some podcasts about the Winter War the other day, and the impressive Finnish defense in which they utilized their maneuverability and knowledge of the terrain to hold the Soviets at bay MUCH longer than expected.

This got me thinking of how fun it would be to recreate this in HWW (either in All-In or substituting Sweden in a standard mode) with the Pan-Asian doctrine. While the name certainly doesn't fit, the unit boosts and overall bonuses seem right in line with this idea.

All this then got me thinking about how interesting it would be to see what other countries could benefit from something like this as a kind of alternate history exercise. Would an Axis France or Poland be able to fend off German aggression? Could an Allies Nationalist China survive against Japan long enough to become an economic superpower? How long would it take for a Communist USA to flood the world with Heavy Tanks and Rocket Artillery?

I would love to see this kind of HWW event mode that allowed players to choose their nation AND their doctrine. All starting units/research trees would remain as they are now for simplicity's sake. What do you guys think?
