That would be my preference but I haven't found any great solutions yet that 1. would make a good connection with the weirdly shaped ducting 2. also connect with an aftermarket vent outlet 3. that is flush mounted and will work with ¾" plywood.I think you would be better of keeping them there and ensuring you can get airflow out of the under platform area.
AC supply to the rear is the priority, HotBody never asks for heat
