I’d rather he befriend another Wookiee than Chewbacca.
Shooting from the hip, I would also hope that we wouldn’t even hear the name Obi-Wan at all, except if we get some Qui-Gon ghostly content. There shouldn’t be anyone interacting with him that the name should even come up. Rebels notwithstanding, he should be genuinely settled into the identity of Ben, such that the mention of his old name in ANH sincerely stirs something up within him. I think that was a real fuckup on their part with that one. But not any worse than a great deal of the PT’s wanton disregard for the organic implications the OT had about the past.

“Obi-Wan Kenobi… Obi-Wan. Now, that’s a name I’ve technically not heard for a long time. Not even last Summer when I had heatstroke and dueled with Satan in the desert.”

“I haven’t gone by the name of Obi-Wan since, oh, I guess the time I thought I killed your father just a few hours before you were born. I mean, I don’t think anyone used my first name the rest of the day before I left to come here, but that’s asking for some very specific recall at this point. I don’t even think Satan called me anything but ‘Kenobi’ last Summer when we fought on my front yard.”

My point is that maintaining the technical disuse of his first name does not satisfy his portrayal in ANH, and that I hope this series does the right thing in isolation even though Rebels (and even ROTS) blew that door off its hinges.
