But with cloning he has a child who is 100% "all Jango". Having child by normal means would only be 50% Jango. Whether that would matter to him or not, I don't know.
Another theory might be that because is supposedly the last of the Mandalorians, having a clone child means that his decendent is 100% Mandalorian as well. Just a thought...
