I gave it a go at trying to merge models, I'm not good with descriptions so just give it a try.
CFG works best with values between 3-6 at 30 steps I tested it with DPM++ 3M SDE GPU Exponential, PixAI doesn't have that option but you can still use DPM++ 2M SDE Karras.
If you plan to use CFG above 6 you'll need to increase the steps, I tested up to 10 CFG with 50 steps and it also seems to work.
VAE is baked into the model so it shouldn't be requiered and clip skip you can ignore it
