The Origins are great as companions, but I am uncertain whether or not that playing them as the MC would be worth it. You miss out on their dialogue, reactivity and interactions if they are just party members. While I can see them as the protagonist of their own stories in a game as interconnected as Baldur's Gate 3 it seems like you are missing out on content, especially when you can keep them all as companions with no cut off point like in DOS2. Provided you make the correct choices.
