Our front door opens into the family room. I replaced the doors and windows in the house in the mid-90's, so now although I wish I had chosen a door with a window in it, I am opposed to replacing the door itself, especially as we will be putting the home up for sale soon.

I had the inspiration this morning that possibly I could install a fixed window ABOVE the door - hence allowing more light in without disturbing much of the room itself. Currently between door molding and the drop ceiling there is 10" of space. Any ideas/comments?
