Okay then my main advice is to start as simple as possible. Choose famous characters, don't use descriptor tags (just let the inherent strength of the character prompt handle it) then maybe a simple uniting dynamic like "arm around another's shoulders"

From there you can start introducing loras and weighting characters to combine less famous characters, though it will want to just make multiples of the famous character without proper weighting, which is annoying to do. It's also just a lot of old school "luck of the draw"
