Thanks for your thoughts. @lazy_gardens: I figured I could get one of those Closetmaid kits and just add 2 pre-drilled melamine boards for the left and right walls. That was assuming the pre-drilled holes were a standard height apart and it would just line up easily with the Closetmaid tower. Guessing in practice that is not the case? - Cleaning products: mostly bottles that I want to store higher to avoid kids accessing them. Would like a small space on the bottom left or right to store a couple folding chairs or a small upright vacuum. - Paperwork - probably about the size of a case of paper. I could probably get away with one of these: https://www.staples.com/Staples-Letter-Legal-File-Box-Clear-140050/product_480548 - Space: The closet is 36" wide, 23-24" deep, and the door is about28" wide, so only 4" on each side is inaccessible for a drawer that could open up past the door. That's why I was thinking a tower in the middle with shelves and drawers. Even a 12" one, plus a board on the left and right sides would leave around 11" of usable space on the left and right sides that I would put shelves in. @AnnKH: I see what you are saying. I think i would like to have the shelves be adjustable though in case we change what we want to do with the space over time. I was trying to make it a little nicer looking but i guess shelves may just be easiest. Thought the stacked shoe storage idea would be nice to have on the left, shelves and drawers in the middle for towels and paperwork, and the space on the right for shelves with containers cleaning products and chair/vacuum storage below that.

One of my kids has a 42" deep closet, about 8' wide. I love his closet. I covet his closet. It's deep enough that he can step inside, he has elfa storage including drawers that he can open without being in the way of the door, and he has room on the sides to hang, see, reach accessories like ties, belts, chains, hats, bathrobe. But, it's not so deep that he can stuff it with gear until he can't walk in it anymore! It's just a reach-in-on-steroids. Your daughter's closet is nearly there, lose a few inches in the bedroom, go to the Container Store, and she's good!

Use a local one.

You could: - Remove the doors - Uninstall their tracks - Remove the horizontal separator and shelf -Leave the existing trim in place (or simply replace the pieces on each side if they get messed up when you remove the separator) Even if you remove all the trim, there is no reason you need to mess with the header that is up against the ceiling. In my case, for one closet, I simply ordered extra tall bifold doors for the opening and didn't have to do anything much about the framing or trim...and I certainly didn't have to do anything with the ceiling. If you want to do normal height doors (80") you can just frame for that and use the space above it for a small shelf-niche. I took out three closets like yours and I recall that I put standard height doors in my daughter's bedroom closet, and the niche allowed about a 6" high space for display of knickknacks. No insult intended, but I'm guessing you don't have a lot of DIY carpentry experience. But if you get a professional to help, I can assure you that they won't need to disturb the ceiling to make the changes.
