I agree with you on that, (but no pilot should ever think it acceptable or correct to apply full pitch up at 36,000 in the first place, no disrespect intended to the AF447 crew).
In theory, the side-sticks could be linked mechanically with a series of 90° cranks and two control rods crossing from one stick to the other just behind the lower part of the instrument display panel, and a release pin in each rod could be pulled in an emergency to separate the sticks.
Knowing what the other side-stick is doing need not require mechanically linked sticks: The Maltese cross and four corner display used for control ground checks could be brought onto both PFDs in flight under certain circumstances, so the other pilot would see what control inputs were being applied, and thus be aware of the need to apply their take-over button if required.
