Default 99 3.8 swap into a '02?

Hey guys so here's my question.
I got a totaled 99 Grand Prix GT coupe with a naturally aspirated 3.8 that is a good motor. And has a good new transmission.
I'm looking at a perfectly good 2002 Grand Prix GTP with supercharged 3.8 that has a rod knocking in it.

Do you think I could put the good 1999 3.8 into the 2002 and put the good supercharger on the 1999 3.8?
And put the new trans from the 99 into the 2002?


Best I can tell is the 1999 3.8 is a 9.5:1 motor and the 2002. Supercharged motor is a 8:5:1 motor.....

But do you guys think it will work?
