Genesis Featured Post Widget Image as background

[Tal]

I'm wondering if there's a way to set up the Genesis featured post widget to essentially display the content (eg excerpt) overlayed on the image.

Eg, I'd have the image fit the size of the widget box, and then the text displayed over the top of the image - the result would like like the image slider (which I'm using elsewhere on the homepage) but just with a single image.

Is it possible to alter the featured post widget to do this or does anyone know of a plugin that will help me achieve this effect?
