From Mario Wiki's beta elements page:
That would have been a pretty dark thing to have in the game, a gun using hunter type ghost wanting to have Luigi beheaded and his head mounted on the wall.
Considering he was supposedly Australian, it also reminds me way too much of a certain member here...
but also makes note of an unused and unpictured portrait ghost who would be a generic australian hunter who would have wanted to add Luigis head to his collection of other heads. He would have appered in the Safari room, and may have been removed due to the fact that his dialogue would frighten younger children.
