Interesting! I always thought that Bajoran freighter was a redressed model as well. EAS theorizes here (far down on the page) that it was cast from the same mold as the Husnock ship, which would explain why it has a generally similar shape.
Coming back to the XL-version of the Discovery, I can now say that I agree with @Markonian's assessment that it's not really a huge improvement over the original model. Unfortunately it's only marginally larger and doesn't really feature a ton of additional detail. For me personally it's still cool to own, because the saucer of my regular Discovery is somewhat crooked, while this one is perfect. For anyone who hasn't got either of those models and is thinking about getting one, I would recommend getting the larger one, as it's just a better size for the ship.
I saw that too. My assumption is that Jein created the Bajoran freighter in that way to show design lineage with the Ensign Ro "Antares Class" redress of the Husnock ship.
