Replace the front panel without changing the display

Can anyone give me some instruction on transplanting the digitizer, lcd panel, and all other parts from the front casing to a replacement one? I'm looking ahead to when I plan on reselling my GS4. The screen is in perfect condition, and I've had a case on it since I first unboxed it. I have however, dropped it a couple of times, and as such there is some marring on the chrome bezel- not the metal midframe. Most people I have seen online end up just changing the whole front panel assembly, but I would like to know if it was possible to just purchase the part I want to replace- which is available on ebay: http://www.ebay.com/itm/Silver-Mid-Metal... and then just transfer all of the components over to the new part.
