Not knowing the answers to these questions, the best that comes to mind is to wrap more neoprene insulation on the refrigerant pipe and put some on the non-insulated return pipe. Follow this by refilling the wall cavity with a Rockwool batt, which is denser than fiberglass and more sound absorbing while also providing good thermal insulation.
Also, installing the PSV on the building return pipe will not change plant operation and pressure control.
