Gaussian blur for fanart

I would like to apply a Gaussian blur to fanart in a skin. Many skins today apply a dark translucency but I would like to go further and soften the fanart so it doesn't distract from the media information. The effect would be similar to Apple TV's effect, though not quite as strong:

Is this possible to do within a skin, on the fly, without modifying the source fanart?

Thanks
