In making new ships that thematically match the default ships we're running into two problems. One is that complicated parts like engines that are conserved across several designs are difficult to replicate. Releasing the meshes would solve that problem, but I don't really expect that.
The other problem is that we don't have the original textures and I think making those available would be both more reasonable and more needed since the shapes can be replicated more easily than things like the hexagonal ringer texture.
