Stable Diffusion using `img2img` might do a better job here than DALLE, since you can give the AI an image prompt as well as a text prompt.

You could make a crummy collage in the gimp or krita (these are open source alternatives to Photoshop).

I'm a bit too lazy to do this myself right now, but if someone wants to play around huggingface has a cool website that lets you do this: https://huggingface.co/spaces/huggingface-projects/diffuse-the-rest
