I would like a show like that but set between episode VI and VII. A Luke Skywalker show a blend of live action and cgi to de-age Mark Hamill. Showing his journeys after the film to find the old secrets of the jedi order, the old jedi relics and holy sites. Studying the deeper mysteries of the force and him setting up and building a new jedi order. Ending with the destruction of his temple and order at the end of the series by Ben Solo.
There has already been a comic series called The Rise of Kylo Ren about this (haven’t read it myself), but it’s not all that popular and could easily be retconned. Some people who weren’t happy with Luke in TLJ say that because you don’t see enough of his efforts to rebuild the Jedi and how crushing Ben’s destruction was to him, it’s much harder to be emotionally invested or satisfied that self-exile is a believable response. I disagree, but a show like you’re suggesting could appeal to them a lot, and I like how it could explore more lore of the Jedi.
