If there was to be a season two, skip a few years to get a graying Kenobi (with a wig that looks like Sir Alec’s wig) going up against some Hutt BS or a force-sensitive bounty hunter that endangers Luke/the citizens of the Dune Sea. Maybe this is the incident that makes Owen go “no contact” with Kenobi (if Joel Edgerton’s salary demands are met/he’s not too busy).
Maybe find a live-action Satine for flashbacks? Her absence is understandable in this story, but it would be nice to have her acknowledged.
Maybe you could have Kenobi have premonitions of his encounter with Maul as well.
The issue there is that Ray Park had a falling out with Lucasfilm. However, any stuntman that looks close enough would work as long as Sam Witwer is still providing the voice.
