Is there a tag for when two character/personas are merged together and split in the middle to make it look like one individual?

I found split image, there are some good ones

but also situations where it’s not split in the middle of the face, or the subject in question is the background

and gray zone

I found split theme and split screen which are similar to split image. Looking at the posts and wikis, their definition are vague and overlapping each other. I suggest decomposing them into more specific groups and maybe make split_theme the parent tag

another question is that would that be 1girl/boy or 2girls/boys?
