Anything can be done if you are stubborn enough. You would have to get conversion bearings, which somebody found but I don't have the number of. You would have to machine custom axle spacers, since the rim is wider at the center than stock. You would lose the speedo drive, and need to install either a gps speedo or an electronic speedo. The brake rotors will need to be reversed, and spacers made for the calipers to set them inboard. When you get done, you will have a heavy wheel that doesn't do anything better than the stocker, except match the rear in style. Most of the good modern sport touring tires you are looking at for the rear, are made in 110/80-18.
