Here is an update of the winning can (I took some artistic liberties with the back of the label to add ingredients and nutrition information to make it a little more real feeling - but the the front of the can and the text down the side are copies of the original).

Thanks to those who have offered help with textures, however I still haven't found exactly what I'm looking for. I got the emulator and text ripper working but the UI isn't overlaying over NullDC so I can't see what texture I have selected. I tried spamming the export button but froze NullDC. Also, the Japanese texture pack has Coke - which would not be nearly as fun to reproduce :P.
