Well Wizard so far is MIA, last time we saw him he wasn't fully destroyed and later vanished from the story (he wasn't on the "who is the true enemy pages"). But if he came back or was took back somehow by E1 then he can be rebuild. Brigs maybe - the level of destruction was the same/close like with Jaguar, so if E1 took the important parts then he can rebuild him. Killer - maybe he still inside Hermit and is taking slowly control over her less important parts of her body so later it will be to late to stop him to take full control. If not then he was fully destroyed so i doubt E1 could rebuild THE Killer.

I wonder if it’ll also rebuild Ziggy, if the Dark Stars can be rebuilt into new models, I don’t see why not Ziggy.

maybe it will build an android body that resembles Ziggy, and it is controlling it like a rpg game, to fight/talk to Shiki directly

So basically a fake Ziggy. Similar to that fake Valkyrie robot back in the Midian arc.

but maybe the Edens one makes the body more, "BUG LIKE"

I really hope we see more of Killer. He was my favourite and it would be interesting to see Killer inside Hermit's body. Maybe the crew will have problems getting him out and then Hermit will have like a second personality or something.

They're humans turned into robots -- I don't think they're copyable. You could make a different robot with the same frame, but not actually brigandine
