As overrated and boring as I think Maul is, I feel like he would have to be a presence in an Obi Wan spinoff. In order for Obi wan to have any kind of meaningful arc, he would have to have that presence. He should be haunted by this demon from his past. When you think about it, this time period is Obi-Wan’s lowest point. He has lost everything, with only the smallest glimmer of hope for the future in Luke. To me, the last step to him becoming the wise sage we see in ANH is for him to, at his lowest point, face and eventually overcome the demons of his past, and what better way to visualize that than to have him face the only thing in his past that caused him to waver toward the darkness (I mean he got pissed off and straight up murdered maul in TPM). Might actually give Maul some importance for once.

I don’t think ben should face Vader. Vader should be a presence, and this should be used as a venue for Obi Wan to somehow learn what happened to Vader after Mustafar, but I think it is more dramatically appealing for their duel on the Death Star to be the first time they’ve been face to face since Ben left him for dead.
