Fly the airplane with guidance from the book, don't use the book to fly the airplane, it has gotten people killed. If auto anything stops working (or doesn't work) you wouldn't say "there's no procedure for this" and give up, would you?
Also if you want to justify your actions on paper:
No action will be taken (apart from depressing MC/MW pushbutton):
-until flight path is stabilized.
Excellent, as soon as you stabilize the aircraft you're free to do what you need to do to keep it airborne. Full (or near full) control deflection is not a fantastic way in which to fly the airplane, not only is the prop causing drag but on some airplanes you've got spoilers coming up as part of the flight controls. You're putting a LOT of drag on the airplane when you're trying to climb, you can take all that drag away by feathering the engine, so why on earth wouldn't you?
