Here's a quick and simple workflow to allow you to provide two prompts and then quickly combine/render the results into a final image (see attached example).
You can adjust the strength of either side sample using the unclip conditioning box for that side (e.g. more strength or noise means that side will be influencing the final picture more, etc.)
