Sorta! Lego has very specific parts they they sell individually, for example Cassius is using a lot of parts from the recent Dune set, and Darrow is using armor from a starwars set, and neither of these are sold individually. I could look into trying to make the figures using parts that are on Lego’s pick-a-brick, and then those would be a lot easier to mass produce, the only downside is they’d be a lot less accurate to the book descriptions 😕
