Small snag in 22

After cleaning up the office, I turned to planning the dismantling and adjusting of my current shelving system. Basically, it is a homemade "L" shaped bookcase that fits into the corner of the office.

I've been using it to hold my DVD collection and a few books, but with the goal of reducing the size of my anime collection, there has been more empty space on the shelves as of late. My current plans are to remove the short side of the "L", cut the height down to fit the closet, and reset the shelves to make better use of the whole shelf system. Well, upon closer inspection, I ran into a small issue.

The larger side of the "L" is currently full of DVDs, and I'm afraid that if I remove the short leg of the "L" the larger side may be too heavy to stand upright on its own. The amount of lean away from the wall isn't horrible, but I don't want to risk having the shelf come down on top of my desk and my guitar stand. The shelf is just over 7 feet tall, but only 8 inches deep, thus the concern.

I think removing the smaller leg will have to wait until I can do a little more planning and prep work. I'm going to have to take down everything in the shelves, remove the small leg, and then reset the shelves in the larger leg to condense the weight to the bottom of the structure. I may even move it and secure the larger leg to the wall temporarily.
