Possibility of phone with k800 front fascia and k810 back fascia???

Firstly, I hope I have this in the right part of the forum :)

Now, what I would like to do is mod a phone to have the k810 back fascia (the camera cover section) and the k800 front fascia (to avoid the fingerprints and get the keypad of the k800)

I was just wondering if this was possible (with either k800 or k810 middle section and pcb) as I think it could look good depending on if the colours are the same. If anyone knows if this will work and if the colurs of the two parts will match please help as I'm needing a new H/W mod to try lol.

Cheers :D
