Like Cummins stated. Glue a piece of wood on to the back of the ceiling board, drill a small hole and you will be good to go. I did this about three years ago. Screws are still holding strong with no striping signs. I am not an Hvac engineer , but there is a balance between intake/suction and out-take/blow. It is a balance of CFMs. I believe that you want suction on the intake side as it moves the air better. Check the vents and ducts for leakage. I would think this would be your best improvement. There should be a thread about this on here some where.
This is a link on basic ducting understandings.

Again, I’m not an engineer.
Hope this helps.
