I wonder if this storyline is the primary reason Filoni was brought onboard? It’s sort of like how Ronald D. Moore essentially became “The Klingon Guy” at Star Trek, because he was more or less the de-facto expert on their culture after reshaping it through his episodes.
Filoni is that for Mandalorians, probably. Especially since it seems almost like Mandalorians are the Star Wars version of Klingons now.
Filoni is probably on board for a lot of reasons. He’s been part of LFL’s unofficial brain trust since the Disney acquisition, so he was probably going to consult to some extent on this regardless. When you consider that Favreau worked with him on TCW in Mandalorian episodes specifically, it’d have been kinda weird if Favreau hadn’t asked Filoni to have a creative role on the series. All that, plus it sounds like Filoni wanted to dip his toes into live action.
Honestly, I wouldn’t be surprised if he has his own live action series at some point. I’d also imagine his stature within the LFL hierarchy will probably increase as the years go on. The incessant fan speculation that Kennedy will be fired and replaced with Filoni is annoying and laughable, but the truth is Kennedy isn’t young and won’t have her job forever. When she leaves, you have to imagine Filoni would be near the top of the list for a replacement.
