I don't know if you're familiar with the Victorian author Wilkie Collins but, as I remember, his mystery novel The Moonstone and possibly also The Woman in White use split-narration. Some of it may have been epistolary, but I remember two of the characters' voices vividly: an old servant who used Robinson Crusoe in place of Virgil for sortilege and a lady who left a religious tract somewhere with every couple steps she took. (I guess his strategy is similar to Faulkner's though, identifying the speaker at the head of each chapter.)

Long chapter titles have possibilities. We're reading Don Quixote in Menippean Satire. Cervantes' titles appear to be giving away the chapter contents but their predictions are always fulfilled in unexpected ways.
