There is a common misconception about moving an incapacitated pilot out of the pilots seat. This is hardly ever necessary, because you can fix him in his seat, with shoulder harness, with whatever comes your way. It's only necessary if laying him/her down offers greater comfort or reducing his/her suffering.
Contrary to above's opinion, a CA in the cockpit offers great benefit, but not by reading checklists aso, but by helping to secure the incapacited pilot, by easing communication to the cabin, bringing an additional crewbag from the closet in the back of the cockpit aso.
As soon as you fly on your own, you don't read checklists anymore, you just do what you have to do, and if there is time you go through them silently. Cockpits are designed that you can bring down that thing alone. So just do it!
