Don;t see why you could not remove the bulkhead, Just seal the door in the picture and open a lid in the shelf behind the upper door like our 37 #249.
I would agree that the anchor locker is a problem. Yours is better than mine as I have a split locker port to starboard that Nigal Calder cut out of his 40 when he took delivery. I have only 1/2 of the bulkhead in your pics. Do it first and I will do it second. Doug Grifith PSC37#249 Kindred Spirit.
