I don't think I can. Or do you mean I should somehow hook into the 
options page created by add_custom_background()?

The Appearance submenu looks like this:
* Themes
* Widgets
* Menus
* Theme Options (My theme's options.)
* Editor

After add_custom_background() it has another one, Background. That's two 
pages for one purpose.
Having just the one avoids the "multiple 'appearance' configuration 
menus" issue, introduced by add_custom_background().

If I use add_custom_background(), I'll have to change it so that it will 
display the special variant of image, specified in my theme's options, 
and, well it just seems like too much unnecessary work. And what if 
there's two images? Or multiple images, different ones for pages and posts?
