Great idea!
You might want to take a photo to the office supply store. Have the printing department enlarge it and make a few prints for you. You might only need one copy but nice to have an extra one. Use tracing paper and make your applique pieces using the method you like. It sounds like a fun project!
PS: There is a special sheer fabric that you can put over the picture and draw the markings. Then make the applique pieces and transfer them to your background fabric.
