On another boat type, our Bavaria Cruiser 41, we intentionally made the aft head door to turn inside. I have noticed on many charter yachts the hinges have broken out, as the door sometimes (when not fastened properly) swings out fiercely during sailing with the original fitting swinging to the outside. For this type, frame profiles are still available from the factory and door is turned upside down to fit again. If this could work for your 2006 Cruiser needs some additional investigation. But with some TLC it would be possible.
