Don't do it unless the visualisation adds some new aspect to the joke. Remember, cartoon is a synergetic coalition of picture and text. Well, that won't be easy. Read adventures and books about adventures. It shatters the very foundation of the story.
Adventure is a deep subject in itself, well worth another article.
If not, be very cautious. Unless your drawing skill is divine, it might not work as a cartoon either. Then, a cartoon with a message. Take a look at yourself. If so, congratulations, but this kind of cartoon is hardly for you.
