Addition of iron blocks and chiseled polished blackstone blocks as allowed blocks on the Cargoship movecraft type would be great. These blocks would be purely cosmetic and would not affect the performance or balance of the movecraft, but would provide more options for players who enjoy decorating their Cargoships.

Iron blocks would be a fitting addition to the Cargoship movecraft type, as they are commonly used in the construction of real-life cargo ships and would help players create more realistic and immersive designs. Chiseled polished blackstone blocks and smooth sandstone, on the other hand, would add a new and unique aesthetic to movecraft builds and could be used to create intricate patterns and design.
