The Star Wars: The Old Republic video game has a mission called “The Face Merchants” set in the Coruscant underworld where Black Sun has been operating a similar operation. Though the technology back then seems way more archaic as it required invasive surgery from specialized droids/software to reform the faces of the criminals, the concept of altering facial appearances has at least existed in Star Wars aside from this one TCW episode.
