Wouldn't it make more sense to create ten streams of images of the same class and then see which one results in the smallest compressed size for a test image?

Wouldn't it make more sense to create ten streams of images of the same class and then see which one results in the smallest compressed size for a test image? That is, if I gzip a hundred '6's plus my test image and get a compressed size for my test image of 10 bytes, but doing the same for other digits gives me say 15 bytes then I conclude the test image is a '6'.
