As a concession to the possibility of a future sale AND in the spirit of more room (we ALL need more room!), why not put either a single door or double doors leading into the room next door? That way you still have two rooms. Most folks would like that because it's good if you have a single child (room next door is the play room), or 2 children, or someone who is like us and has a hobby they have a passion for. You could put your long arm into the next room, and put bookshelves wall to wall on one wall for tons of storage in the other room. Keep the closets though, or the room won't count as a bedroom when selling.
