CTS V supercharger on a 5.3?

I was looking at aftermarket superchargers a while back and noticed that many were compatible with different types of LS style engines. I have found a 2008 CTS V  with the supercharged 6.2L in a junk yard is there a way that supercharger could work on my 5.3? I am just curious because after talking with them it is a lot more affordable rather than buying a new whipple or something similar.
