A well detailed review as always! Glad to know he's about as how I expected him to be. He's a must have for me.
As for his clan members, it's probably just pure aesthetics. All 3 are kinda cyborg like and that's it. I don't know if Neca has given an explanation as to how the Borg Pred from the Lost clan can be included. But it's easy to head canon. Maybe this group was where Borg used to be or maybe his future clan, who knows?
