I really doubt that, as i've read a report about Aileron tests on Spitfires in 1941 where is written that the Spitfire Ailerons loose 65% effectiveness at 400 mp/h because of wing twist, and that 54 lbs force are needed to get a 3°deflection on them.

Aileron reversal speed at 10000 ft was 477 mph ias.

The Rudder and the elevator of the 109 did get very stiff at highest speeds, but the ailerons also? And more that the spitfire ones with their reduced effectiveness?
