i've seen a couple of instances where a super chunk was used in conjunction with a door but it's usually hinged on a frame or mobile to slide in and out. in most cases, it is easier to just go with a flat absorber on the door. i'd go with pic 3 the panels peaking into the room at the center.
FINAL DESIGN before installing --> pls help to check is ok
