They have already burned that bridge by doing CO2 to distillate.
Leveraging the expensive equipment they have to get terps while they still have value makes sense. Doubling down and getting another CO2 rig to feed a wiper seems dumb, even if you can pick up for almost free. Which is doable.
I would explore their reasons for going CO2, it might inform your suggestions for alternatives.
Pretty sure I could make a decent espresso machine out of a free CO2 rig, and @moronnabis reckons you can get this cat skinned good and proper with three buckets and a buchner using water without the espresso machine.
