JD-EE:
In normal situations the 'feedback' will be noticed by PNF.
If PF SS input is 1G climb (ANU), PNF will experience a 1G climb and knows PF pulled the stick (not to the max).
What you are suggesting is an interconnection with both SS (Bus bar or by Electric synchronisation) and in abnormal situations you want to disconnect this synch.
A lot of engineering ahead for a feature which will be of -no use- most of the time.
There is a visual indication of resultant SS inputs on PFD on ground.
