I have noticed when clicking on some of my designs and clicking redesign with no changes to the prompts and current prompt options, I get images that are not noticably differernet from the source image.

Some other image generations add an editable Random number (to thier image generation options) that can be changed to get noticably different results.

Another apporach I have used from other systems, is they have an editable % for Prompt guidance, which gives the AI more or less percentage of how close to the original image or prompt, we want the new image to emulate.

Either or both or something new would be a welcome feature for us to guide the AI into more or less emulation of source image.
