By definition a stalled airfoil is in its very highest induced drag state the moment it begins flying again since it is at maximum AOA at that moment.
Form drag during a "tumble" is tremendous. The stress on the airframe is tremendous.
While aerobatic tumbles look like chaos they are actually carefully planned and executed maneuvers.
In modern aerobatic aircraft with extremely high thrust to weight and structure purpose built for the extreme stress of these maneuvers, Lomcovak's and other tumbles are routinely performed. However, they ALL require a brief period of extreme nose low attitude to regain flying speed.
The forces involved in this things wreaks havoc on aircraft structure, with engine mounts most susceptible to failure.
Doing these things in WWII era aircraft is a fantasy that would rip the engines off these aircraft if attempted.
The ability to recover from one without reducing the pitch 45 degrees below the horizon until speed builds is only possible in a radio controlled aircraft with power to weight in excess of 1 to 1. Nothing manned can achieve that except a jet and jets lack the gyroscopic forces necessary to create these tumbles. (There is one jet capable of the lomcovak)
Plain old snap rolls are possible in just about any aircraft but again require pitch reductions to recover flying airspeed for a brief period.
What we see in AH with regard to post stall nose pointing at high AOA is pure fantasy.
And that is okay. It is a game and its good for the bottom line for Hitech to create the feeling in his subscribers that they are masters of virtual skies.
But lets not pretend it is reflective of the real world.
First if your going to speak of flight modeling at least start by getting your terms right.
" nose pointing at high AOA" Is a completely nonsensical term. I assume you mean nose high relative to the horizon.
Ive personally done snap rolls in many different airplanes including p51's at about 45 inches of Manifold pressure during air combat . The recovery did not require nose low, but simply a quick unload and hard opposite rudder would hook the plane right back up. I've done inverted snaps by accident in my rv which also did not require any nose low.

Ive also done Lomcovak's in an older yak. And I don't believe if you manage to do one in AH you could recover with out nose low either. In fact to accomplish the maneuver it requires very low air speed at the correct time and the plane just becomes ballistic.
As far as could the fighters of the day take the stresses of tumbling maneuvers? I would be very surprised if they couldn't.
