Great Idea
I did the same thing on my 36. Take out the closet pole. Get a few big pieces of cardboard to make templates, and then cut the final shelves from 1/2" plywood. I put in two shelves, roughly dividing the area into thirds. The inboard edges of the shelves can be recessed back a few inches, and you can put small coat hooks just inside the doors so yo can still hang a few items if you want to. If you put a fiddle on the inboard edges, the stuff you put on the shelves will not fall out as easily. Paint them white to reflect more light. Good Luck.Tom soko.
