I know Favreau's name gets tossed around a lot, but would he even want the job? He seems to like jumping around, directing a random assortment of projects ranging from Chef to Iron Man to Jungle Book. Obviously, he is at the helm of the Mandalorian and seemingly liking the role, but taking KK's job would basically require a full-time commitment to Lucasfilm, and I am not sure if he wants that for the long haul. Filoni loves Lucasfilm and does not seem to have an interest in leaving, so he would definitely be okay with the long commitment. He is personally a huge Star Wars fan and really understands the fanbase. The Clone Wars was his brainchild and very well received by fans, especially impressive given he had to work with Cartoon Network, then Netflix, before concluding on D+. He is also very involved with the Mandalorian, which is obviously seeing much success. The only drawback I see is that he comes from animation and Lucasfilm's biggest projects are live-action, although he does have extensive writing experience and is gaining live action credibility through the Mandalorian.
