The images are just stored as compressed PNGs, so the overhead for having theme separate is the normal PNG overhead. Whether one way or the other will be a win depends on how much they compress in the two different configurations (which depends on the contents of the images) as well as the overhead per image.
It shouldn't be too hard to implement your own SpriteDrawable if that is what you want. Take a look at the BitmapDrawable code as a place to start.
