Use a slider widget as header image

I am experimenting with a new look to my site. My experiment site is test4.franciscanfriars. I am randomizing header images... it is nice... but I'd like to have a slider widget as the header image. I built a slider widget on a page called "test header" that you can look at if you like. is there a way to use this widget as the header image so that the image changes as people look at the page? thanks
