I completely agree! With a BD1 droid appearing in the Obi-Wan show proves they have played around with it! I also love how the Zeffo from Jedi Fallen Order have been referenced in season 2 of The Bad Batch! So its very possible we'll see some form of Cal Kestis. I love Cal and I would love to see more of him.
They have so much lore in just the course of 2 games plus, may I remind you that we saw the Inquisitors and the Fortress in Obi-Wan as well. He would make for a perfect Live-Action character.
