Nice idea.

I’d like to review and test this.

only minor issue may be that I wasn't sure about the 1 pixel offset and couldn't pixel peep to tell so the image is 1 extra pixel on x and y

It looks like the feet of the guests are cut off, presumably because this was taken from one of the default paths that cover them? For this path, it makes sense to show the feet properly. Perhaps recreating this setup, then creating a very small "giant" transparent screenshot is the easiest way to make it work.
