Another candidate that fits the arguments in the article would be Aragorn, who (as Thorongil) served in Rohan and Gondor around the time Faramir was born. However, even if we ignore Tolkien's general conservativism, it is unlikely that Aragorn would ever cheat on Arwen; they got "engaged" just three years before Faramir was born.
