you can do what you're asking if I am understanding your post correctly.
simply understand Steam Family Sharing, and you will be able to play games in eachother's library.
that is, you will be able to play a game from his library, and he will be able to play a game from yours at the same time, but you will not be able to play a game from one library or two games from one library at the same time.
games bought on Steam are not transferrable to gog. just as stuff bought at sears cannot be returned at costco.
