There are huge engineering avenues that haven't been explored at all in this regard. As I said, all contemporary aircraft have large wings in part because they have to maintain high lift at low speeds, when landing. There is a big likelihood that some design compromise could be made where a lifting-body design, foldable wings or similar concept could be used to make a much smaller and more lightweight vehicle. A more realistic answer to your initial post is that we don't know yet, not that it is impossible.
