This is a workflow I've been playing with today based on my SDXL workflow. It's not fancy. It works. You have to sort out face detailer if you don't already have it's requirements installed. Make sure your comfy is up to date to get the nf4 nodes. This isn't beginner friendly. It's more an intermediate user time saver.

This workflow has NSFW elements.

I'm using this on a 12gb card. You may need to dumb down the upscaling models or make other adjustments. If you're using a card with less than 12gb, I make no warranties on the facedetailer. Every once in a while it OOM's on me.

I'm fairly confident all the nodes used are available via the manager. I hate node dependency hell. If you find I used something not easily gotten, yell at me. I'm sorry.
