While this type of translation is heinously understudied, the opposite problem of controlling the politeness forms of translation is actually an important area of research. For instance Controlling Politeness in Neural Machine Translation via Side Constraints (http://homepages.inf.ed.ac.uk/abmayne/publications/sennrich2016NAACL.pdf http://homepages.inf.ed.ac.uk/abmayne/publications/sennrich2...) is something that OpenNMT can support.
