I am going to stop you right there.First of all, Star Wars world building is quite deep
Any depth in Star Wars world building is in response to the shallow world building Lucas did. It is an intentionally shallow setting so they can throw anything they want in it, from old west gunslingers to kung fu witches to ace bomber pilots. Then, sometimes, some writers come up with a bunch of lore to justify those things -- but even when they do that, they don't tighten up the overall setting world building because they still need to be able to add anything and everything to the setting.
