To be fair though, you don't really want any of these things in your spaceship either, ideally speaking!
It really depends on the limits of Protean "flesh", I guess. If they can form organic replicas of the containment structures required to hold these things, I don't see why they shouldn't be able to use them in much the same way races with conventional technology do. They don't seem particularly more vulnerable to energy weapons than other ships.
Still, it does seem like a lot of effort to go to when you can just hurl chunks of yourself at people.
