Eco-versions of the Hindu pantheon would be so sweet. I'd love to work on that sort of project. It sounds right in line with another project I've been wanting to work with lately -- meshing yoga asanas with pictures corresponding to the asana names. Remember Shado's Vrksasana? http://www.livejournal.com/users/theart
A picture book of these types of images would be cool, but maybe an online book would be better so that the images could be animated. There's certainly a lot of possibilities here.
