I don't see anything in that list that would allow for this to work.
The main trouble I see, is when you rotate the motors forward, you lose your roll, and it will turn into yaw.
As a tricopter, to roll left, the right motor speeds up, while the left one slows down. The problem comes when you transition to forward flight positions, and you try to apply right roll, the left motor speeds up, creating a yaw, effect, instead of roll.
