You can make anything you want for yourself people do it all the time. Just think about a Comic Con convention... how many people make exact duplicate costumes of say Predator and walk around. Even haunted houses buy licensed Mike Myers masks and use them to scare people inside a haunted house and nothing happens. Does anyone honestly think they go around trying to find every single person who's creating their own fan version of something... nope!
In fact many of the movies you see are based on PUBLIC DOMAIN works, meaning even you could make your own version.
Disney has made BILLIONS on public domain works like Snow White, Cinderella, Peter Pan and more.
I wouldn't worry about a HOME PIN ... things would change drastically if you started a company selling licensed products.
Look at pinball shows people make unauthorized artwork from movies and sell limited copies... that is flat out illegal but no movie studio is going to try and track down someone selling home prints. Not saying its right just under the radar so making a home pin no way anyone ever knocks on your door.
