Hey everyone, I've been a long time "viewer" and I'm just about ready to buy my first car

I really like the body style of the 06+ Coupe but I might as well try to pick up an 09, but the 09 Coupe Grill/Bumper isn't really pleasing to me :P
What I was wondering is if I were to buy an 09 Coupe Si and later on decided to swap the Sedan's front bumper and grill would it be a "simple swap" or am I going a little over my head?
