I really like the spy idea for TOP SECRET, but as for my own ideas, I can really only think of one for Violet Sauce. I don't picture Sin City at all, but instead I see Namie in typical music video scenes (i.e. on a bed singing) with violet and gold color schemes. And then I see her later in the purple military dress from LIVE STYLE 06, and doing intense dancing. I say I see her because it's my vision, haha
