Just wondering is it beneficial to run both a supercharger and turbocharger on the G8 motor?

I have a set of solo axle backs for the v6, thought I'd list these if anyone wants it before they go to the scrap yard. Used for about 3k miles, no gaskets or replacement bolts included. Asking for $200. Available for pickup in the Chicagoland area. (Will ship for $275) Post will be ignored...

My plan is to swap my LY7 and drop a LQ9 into my G8, now a lot of things need to happen for this all to work ECU, trans, front suspension, driveshaft, new exhaust, torque converter, new diff ratio, wiring harness, Im trying to find out if there is anything else i am missing ive been told to...
