In the novel Haroun and the Sea of Stories, Salman Rushdie has made use of Hinglish in a rather interesting way. Rather than use Hindi words conversationally as it were, he is using them for names, and as a result telling a little bit more about the character right off the bat. Very much so a way of making the writing more readable to an Indian reader.
