Would not be a Pink Floyd license for the reason's mentioned above - Gilmour and Waters just would not let it happen.

If it was a music theme, it would have to be Bon Jovi. I'm not a huge fan, but they seem to have a big fanbase over 25 years. Metallica would also be an obvious choice, and if the rumors of Ozzy rejoining Black Sabbath are true, then a Black Sabbath pin would be a great idea.

Captain America would be a great theme. I think Stern have turned the corner with Transformers and AC / DC.
