I'm unsure it is possible to translate the Netflix-Marvel series' success to non-Earth stories, let alone to Star Wars. To have the deep stories that you enjoyed they need enough screen time to tell the stories. The 4 individual stories + 1 miniseries of the Defenders is supposed to be about $200 million [1]. That comes out to 26 + 13 + 13 + 13 + 7? = 72, which is $2.7 million per episode. This uses mostly existing sets and straightforward special effects. Star Wars in particular is commonly set aboard complex spaceships or vastly different alien worlds in the company of aliens and robots. Therefore the investment required to initiate this seems like it would be significantly higher.
Game of Thrones, for context of a series with both well known actors and amazing sets and effects, is about $10 million per episode. If we assume that a Star Wars series would cost about the same and it would take approximately a similar number of episodes to tell such a story, that would be $720 million. I might be wrong, but I don't think such an investment in film has never been done before.
I think it will depend greatly on both the continued success of the Marvel TV shows + how the remaining Star Wars films perform.
