At risk of angering the corsair fans I have to point out that the corsairs cant really manage capships. They are depended upon what they can steal to survive. The materials to build large cap ships would be immense. I don't think the corsairs have the resources to pull it off. Heck if you dig deep enough in rumors it is said that the Titan was originally developed by Kishiro engineers. That means it was once a civilian ship. Or intended to be. The design was likely stolen.
The outcasts have the diverse fleet because they have the money and the pull. They are more of a Mafia than pirates.
Outcasts survive through manipulation. The corsairs survive by theft.
