For those who care:
I received a decision today from FAA headquarters. It states that the "policy and procedures in place at (my airline) are in compliance with the applicable regulations." "If the Captain elects to land on another runway that is shorter, (the weight listed on the landing chart is less than the actual weight) the aircraft is legal to land."
In a nutshell, FAR 121.195 governs dispatch and takeoff only. It is NOT limiting for landing operations.
