I'm probably biased as the document submitter, but this was probably one of the single funniest goddamned episodes ever.
A few things included in the doc that were not used in the episode:
Bevel Lemelisk, the guy who built EVERY weapon of mass destruction in the Star Wars universe.
Callista Ming, Luke Skywalker's love interest in multiple novels who was the ghost of a dead Jedi. Luke repeatedly made out with her while she was possessing the body of one of Luke's dead apprentices.
Waru, a giant, inter-dimensional pile of meat covered in gold plates that ate Jedi
The Yuuzhan Vong, an race of extra-galactic sado-masochists who only used organic technology and killed over 300 trillion when they tried to invade the Star Wars galaxy
That snow monster that tried to eat Luke at the start of The Empire Strikes Back, who later rallied an army of other snow monsters to kill Luke Skywalker when he briefly returned to Planet Hoth in the novel Darksaber
Some stuff I came across but didn't include in the document because it was too inside baseball for the podcast:BoShek
