Is there a plugin or system where your WP blog's theme refreshes to a random new theme whenever a NEW visitor loads a page/post? Obviously, the theme won't refresh to a new one until the visitor's cookie expires. Fresh new theme with each page/post load might make the site look like an online version of a Carlos Castaneda wet dream.
I'm asking because bounce rate is fast becoming a larger issue and maybe finding the most traffic friendly theme would shave a few points off BR. Obviously, BR is more a function of content quality/the amount of thematic similarity between the referring keyword and actual post the traffic lands on/and a list of other variables.
