You can do that and it would work. However your tranny isn't gonna like them with it being an auto. Do you have any transmission upgrades? Or is it just completely stock?
Honestly if I was you. I would go ahead and start with your transmission first and get that taken care of and out of the way. I would look into a Torque Converter and Valve Body as well as an input shaft and depending on how much you tow, I would look into an output just for safety precautions. The 48RE tranny is only good for only 65hp or so over stock. You get those few upgrades that I mentioned above.. you should never have to worry about your transmission. Safety is a very very big thing in my book, lol.
Other than that. I completely and totally agree with everything that cummins04.5andshaker said you could also look into the stocker over A5k setup which would be another great combination of compounds if you want more information about the aurora's let me know they are a freaking sweet turbo in my opinion has served me incredibly well in my setup as a single so I know it would be great which a compound. But all in all you get that tranny safeguarded and you're good to go.
