2002 LS 3.4lt

Does anyone know if you could put 3.8lt heads and super charger on the 3.4lt. I just bought this car and it has spunk but I NEED MORE! I didn't want the SS for insurance reasons. I'm a mechanic so i'm thinking this will work if all bolt patterns line up and everything just need to know if it's possible. and if the lower end can take the abuse. I'm not worried about the tranny. So if you could let me know thats AWESOME!
Thanks in advance.
