Different splash-screen images at each login?

Is there a way to set up a rotation of different images to appear at the login splash screen (where the green jellyfish now appears in jammy)?

So that each time you login, a different wallpaper image appears at the login window (let's say you have a dozen images you want rotated).

Might there a be a script, or an app, out there, or any other way to do this?
