Of course, you can do that to.
You know Frink, for a time your "Thread is now about..." was about a specific subject where I saw perhaps 3 images of a creation I was involved in, and probably saw one of "my" creations in there. I smiled and didn't say anything for two reasons: 1) of course to remain "anonymous", 2) simply because such creations justly don't belong to me anymore!
Star Wars is sure a solid rock for creation, but it would be *imho* a mistake to use GL's material to tell a better story of Anakin Skywalker.
... How a young skilled pilot, or whatever he is, met an apprentice of a magical discipline, and how he turned wrong and betrayed his friends, or a spiritual order... That, you really don't need GL's stuff to tell it, and certainly not paste the name of Star Wars on it.
