Yes, I do indeed plan to add a tinier mast for the remaining length, so it will be the same design as the brig which is the first image of page 3. Similarly spars are planned upgrade. Similarly, at least a few paper sails. Another thing I plan to do is a balcony on the rear- you can glimpse the balsa wood part which is destined to go there in one of the pics. But not planks on the outside surface- that part I'm satisfied with.
