yes pekin will breed with pretty much any of those. I have ancona and cuyoga and pekin...and they are all really sweet..my buff hens are super sweet, but my drake was not. Also the runners are pretty sweet and they come in light colors as well. I have a buff and runner cross which is very pretty..it was a chocolate runner with a fuff and the color is a really nice darker tan/ fawn color..pekin with a cuyoga would probably be pretty , but you'll get some darker markings. I'd breed for temperment as well..someone here said calls..i would nto breed a call and a pekin..i don't even know if that's possible, but calls are too small for that. I try to breed true to the breed fro show..some of my ducks do cross breed, but i also have pur buff babies, and such as well.
