I think the topper has to be Cara Dune - right? ...sorry, bad joke. I don't really think I want to talk about that anymore than has been already
I like the IG-11 idea. I don't think having Grogu in two places or another Mando helm sounds that great to me - ...maybe
I was honestly hoping there maybe some cool thing - droid of some sort from season three that would be a good fit. I mean without Grogu they need something to take his place. Even if it's just a few episodes I could see some r2 or bb-8 like character taking that spot.
