I think we need to be extremely careful about trying to forge any links to Greek mythology. Western civilization has named a lot of celestial objects after Greek mythology. Often times this was intentionally done so that the celestial objects could be used to tell a story. The links between celestial objects and Greek mythology are the links that humans creatively ascribed to them thousands of years ago. The fact that we can go to a place intentionally named to make people recall a make-believe story doesn't mean the story automatically has truth to it.
Orion chasing the Pleiades isn't "interesting" and a sign that we should go investigate Orion any more than going to Disneyland and seeing Donald Duck means that Mickey Mouse is real we all have to go save Fantasia.
