On my site we use several skins on different pages, we have a Homepage with a large background image. 

When we are getting ready to change the image we have skins that have the different logos, and text colors so they stand out depending on the image. ( dark images, we go white, light images we revert back to default colors )

I know you can view preview your site in different skins, but not specific pages (i know u can, but there is no UI for a user to do that )

I am looking into adding button/link on the pagesetting.aspx that does the whole gray box thing showing the current page, with the selected ( not yet saved ) skin.

I think this might be valuable addition to the CMS. Letting me as a developer not have to hold my users hands as much :) 

Thoughts?
