I can not see any reason a B200 would go into reverse thrust uncommanded. Flying a B200 single pilot and no passengers, on a test flight, I would guess TOW at around 10,000 lbs. That would give a take off run on a cool day of around 1600-1800 ft maximum. Its going to accelerate quickly and there is a tendency to rotate a little early with a higher than normal AOA. You lose the left engine, are on the bottom of the airspeed window, you don't raise the gear, lower the nose or retard the right engine, you will be on the edge of VMC. Then you bank into the failed engine trying to return to the runway and the little margin you have is gone. All twin engine training I have had with a engine failure on rotation in both props and jets is to fly straight ahead until you have airspeed and configuration under control. If you are below VMC you retard both engines and crash/land straight ahead.
