THe only other option I have, is to do the Intro Smoothie in exposed lug, which is similar to the link below. It will be a little different, since it can be done is a smooth outer lip and have exposed lugs.

The unfortunate part, is the pricing will go up quite a bit going this route, especially going to a 22x12.
