I'd only mix pekins in if i ended up with just 1 muscovy female. I really just want a trio or quad of them, but I just don't know duck ratios very well. I literally didn't do anything with my last ducks, I didn't know they needed things different than chickens did. How none died or got sick honestly is a mysteryStatistically ordering six of something guarantees a pair. I wouldn't mix other breeds/species of ducks with Muscovy. But I don't like mutts/mules. Muscovy are in my opinion cleaner than the other types of ducks. They don't spend as much time in the water. they are more like geese in that regard.
