If the aircraft is STABLE at ACA/H for one engine landing (OEI), why now apply additional flap (normal two engine landing flap) requiring additional power, and retrimming. Running the risk of destabilising the approach?
Why not just keep the approach flap for the landing, and avoid increasing the workload at this critical stage?

Aircraft performance being the controlling factor in all discussions.

Just looking at the DA42 extract from COWS GETTIN BIGGER, a figure of 800' for the OEI decide point is remarkably high. Various combinations are then mentioned.....should you be flying a light twin in the first place with significant turbulence and windshear.
Notwithstanding the predicament you find yourself in, clearly a diversion is called for.

Anyone remember the Seneca 1 performance OEI.........now that was scary stuff !
