Both would have great soundtracks.

GnR would have Welcome to the Jungle, Paradise City, Sweet Child of Mine, Your Crazy, Rocket Queen, You Could be Mine, Don’t Cry, November Rain, Live and Let Die, Civil War, Patience, Garden of Eden, it’s so Easy, Better, Street of Dreams... and so many more.

Van Halen could have those sweet Hager tunes like Right Now, Best of Both Worlds, Summer Nights, Why can’t this be love, Best of both Worlds, Finish What ya Started, Pound Cake and you would have a winner. Through in a couple Roth era songs like Running with the Devil and Everybody Wants Some for the diehards and you would have a solid little pin.
