The same observation can be done when standing near the cocpit.

No it can't.

My spouse wouldn't even reach the rudder pedals.

I don't think it's necessary to check the rudder pedals on POH. I can check it
myself when in the cockpit just by the mass of the feel.

I would like to hear arguments against doing a PCC the simple way - PIC
standing outside the cockpit moving stick and rudder and observing the
controls while the assistant is holding the control surfaces.
Again, the simpler it is the more likely it will be done.

And that is EXACTLY how the standard cirrus was checked, and the pilot died.
Frankly, IMO, it's simpler to have the assistant outside the cockpit (I never
said have the assistant in the cockpit) moving the stick away and towards me.
