For the love of flying, next time you are out flying do a few 360s on instruments only while there's a decent wind blowing. You will feel absolutely no difference during the turn regardless where the wind comes from. Your frame of reference will be the airmass you are flying in. It has a constant speed, no acceleration. You are in a constant turn so only feel the extra push into the seat. If you were right, it would be impossible to make a 180 with a TAS of 50 flying in a 100 kts wind without stalling/ripping the wings off.
1 Nop, the moment you make your turns relative to the air, your ground speed (vector) will vary and as such, you will experience (minimal) accelerations.
2 The forces (except the inertial ones) on the airplane are relative to the air around the airplane. With 50 Kts airspeed in 100 Kts wind, this accelleration effect is no longer "marginal", though, because the 360s aren't snap turns, still relative mild forces.
You do forget, that when your airplane mass is not unlimited, the moving air will accelerate the airplane relative to the ground in the direction of the wind. With a light airplane and sufficiently large 360s, this is hardly noticeable, though it happens. And because that effect is happening, you will need to juggle the engine power. The effect is the most, when you turn the nose through the direction of the wind.
