CallMeACynic Yes you sure can. But don't expect to get all the small parts. For example the rubber on the top of the bottom hinge, and the metal bracket which determines when the phone is open or closed. Basically it's doable if you literally take off every small part and build the new housing. A little warning, it's a real pita. So do it at your own risk. Aside from waiting a few weeks before getting the parts.
Just so you can see for yourself the difference. Go to globalpartsdirect.com and match up the parts. You'll see some have small parts.
