That’s part of the side productions we have seen with animated like Rebels now live action on both streaming and theatrical like The Mandolorian, Solo and Rogue one.
The Mandolorian didn’t involve Luke until the last half of the last episode Rebels and Rogue one in cameo as well.
Among the confirmed production for Disney Starwars are Rogue squadron, and something based on the Old republic timeline. However the old EU is not canonical to Disney and the new canon yet the new canon has barrowed from the old with references to Darth Revin, Admiral Thrawn even vehicle designs from the old Toy lines have appeared as canonical.
It’s also likely Mandolorian will return to see what happens next. With some open ended plots from tears ago outside the
Skywalkers. In Example, Dave Filoni ended Rebels on a cliffhange that could be the basis of a movie, series or an arc in Mandolorian; the Fate of Ezra Bridger. His work on launching the last season of Star Wars the Clone wars this year proves that one day he will end that cliffhanger. In fact the Mandolorian already touched on that when We saw Asoka Tano demand the location of Grand Admiral Thrawn. Disney really has worked to canonize the Cartoons in a way. Solo with the Darth Maul living and criminal empire cameo, Asoka and Thrawn in The Mandolorian, Bo Katan Kruyze with the Dark saber in the Mandolorian, Rogue one with Saw Gerrera. These were all Clone wars and Rebels canon treated as solid canon brought to live action productions.
