It could be a slight modification to the Lusankya's hull. Forget the superlaser. Instead of the cargo hold the place would be the weapons armory. How about Thrawn as Calvin Hockley? Isard gets into the shuttle(women and children first you know) then Isard jumps out of the shuttle because she won't leave Palpatine.(lets skip ahead a little bit) Thrawn sees that Ysanne loves Palpatine. Pelleon pulls Thrawn away. The start to walk away when Thrawn grabs Pelleon's blaster out of his holster. Thrawn fires blaster. Palpatine: "Come on! Move Ysanne!" Then there is music during the staircase chase on Titanic but instead it's the imperial march theme. Then after the chase. Thrawn laughs. Pelleon: "What could possibly be funny?" Thrawn: "I put the krayt diamond in the coat. And I put the coat on her!"
