I agree
Old Fella - with the Captain incapacitated, the F/O should certainly remain in the RH seat, where handling will be much more familiar.
As far as seeing the F/E panel is concerned, you
can do so from the RHS by leaning left and back from the seat, and then turning to the right, which gives a good view of most of the panel. I've done it many times. You can even reach some of the fuel pump switches with the right hand from that position.
