Asymmetric in a steep turn

I occasionally spend time getting photos like this out of the side window of my Aztec. As you can see, this entails doing pretty steep turns at relatively low level over built up areas, and I am therefore concerned about the effect of a failure of the inside engine.

The Aztec is a very conventional 6 place twin piston aircraft with two 250hp lycomings, MAUW 2.3 T

I am thinking of going and doing some experiments, at a safe altitude, cutting the inside engine during a steep turn (maybe starting at 45deg and building up to 75deg.)

Obviously I will build up from a gentle start to try and avoid surprises, but I am concerned as to whether a point will arise whereby I could enter a manouevre outside the capabilities of the aircraft (obviously ranging from structural damage to the unrecoverable.)

There is no point in my seeing what will happen in an unlikely scenario only to kill myself investigating!

The aircraft is not cleared for intentional spinning, but is very conventional in all other respects, so I am pretty confident that it would recover from a normal spin, but is there any chance that it will flick inverted?

Any sage advice gratefully received.
