Narrow rear end and a 5 inch BS wheel

I put this post under wheels and tires with no response, really the only guys who would do this are in here....I want to narrow the rear 2.75 on each side and put a 5 inch BS Convo Pro with a 325/50 Drag Radial, I have tube billet lower control arms, on paper it looks like it will fit....anyone tried it? Look good ya think?
