Slingshot, I understand what you are looking for, but I think what we are trying to say is that it seems unnecessary and very narrow scope (you are the only person who would seem to want this). Most people are fine using the regular covers, or if anything would want a full-set cover for the trilogy or something (like for the 2 Wii games and Pikmin 3 on the Wii-U).
Not many people even have both copies of both games. All I'm saying is, if this is something you really want to pursue it's probably something you should undertake yourself.
