Is it possible to swap the front of a 2005 Subaru WRX STi onto a 2006 or 2007 STI ?

I am looking to purchase a 2005 Subaru Impreza WRX STI but the options is limited. I was wondering if it would be possible for me to swap the front end of the 2006 or 2007 STI with the 2005 front. I'm not too much of a fan of the 06-07 aerodynamic front end.
