One simple way to go about it might be to take the closet door, frame and all, and put it in the bedroom. You might even be able to use the bedroom baseboard on the new plain wall in the hall. I like the idea of leaving a small broom closet or linen closet in the hallway, but then you need a new (or new old) closet door. That's still not a problem unless you particularly want perfectly matched woodwork throughout the house, which is STILL not a problem if you have the skill to fabricate new bits yourself.
I've had the bypass sliding doors, and I'd rather have had the wall space. But that closet wasn't deep enough to walk into.
If this closet is four feet deep, a single door would do.
I'd allow my child to choose all the decorations, within whatever limits you choose to set, like
If she wants something over the budget, she can help pay for the overage or make a compensating cut elsewhere
No painting of natural woodwork
Only strippable wallpaper, or we get to approve the wallpaper
etc.
She might enjoy going to the salvage yard and shopping for a new/old closet door. I know I would! But I've always been an old-house girl.
