Glad you crossed back to the dark side, congrats! As to using a 6mt wheel on a DCT, no can do. There are cutouts and two threaded attachment points in the DCT wheel. The back covers are not back covers. It is all molded to the wheel. I suppose you could cut that area out, but you still have the lack of threaded bolt holes to be able to attach paddles. I have seen exactly what you want , but yes, pricey. I think you will just have to belly up to the bar and pay the price. Good luck!
This one is a sport wheel, but the only issue will be a slight relatively unseen gap where the paddles go in at the back as the cutouts are a bit bigger.
