Topic: Replacing a composite image?

I came across an image I suspected was a JPEG copy of a PNG image, but I found that it was actually a JPEG of two PNG images from the same Pixiv post stuck one on top of another.

post #1594640

In this case, should I try to 'replace' this post with one and upload the other, or upload both separately and flag this one?

_{(not sure which category this topic should go in)}

The latter. Upload the "replacements" as normal posts parented/childed together and then flag the old one as an inferior version of the "replacements".
