Use Fresnel lenses with a shorter focal length and reduce the depth.
It would be useful to start with a standard home-type window from, say, Home Depot, and build a unit about 120mm deep using multiple shorter focal length Fresnel lenses.[1] Then, in a basement or windowless room, mount some of these into a wall. Add curtains. Nice if your home office or workshop is in a basement.
This has commercial applications. Houses have few windowless rooms, but commercial structures have many.
