Not to shoot your idea down, but I agree with the other comment. But, to answer your question sure I would sell my designs. Who would buy them is a different question though. Like the other comment, what stops a potential customer from just downloading my page, stylesheets, js files, etc... and making them their own?

For unique templates, companies like TemplateMonster have made a good business for themselves selling web templates though and I would see them as your primary competition in this market. With their brand recognition and affiliate program though I would find it difficult to believe you would have a chance at competing against them unless you developed a different, better, pricing model and provided better services (i.e. include template customization or css conversion at no charge for customers).
