If I'm understanding this correctly, it's a long, rather narrow space and you want to eliminate the linen closet so that everything isn't all in a row. Is that right? Assuming it is, you could consider a lovely vanity, surrounded by an arch, then the toilet, and at back of space, place a closet across end of the room. It can be as deep as necessary to fill the space. That way your room appears shorter but still offers storage for linens or whatever. If I were writing a thriller, that's where I'd stash the dead body. See the vanity in an arch idea in the photo below and note how the vanity area was very nicely lighted by sconces. photos https://www.houzz.com/photos/mediterranean-powder-room-mediterranean-powder-room-austin-phvw-vp~693607
