Somehow, I don't think it's possible lore wise - it took Sharlayan over fifty years just to build the Ragnarok after all (and that was basically poaching the greatest minds in Hydaelyn and still required the combined efforts of every nation on the planet working together to source materials and components required, helped by the deadline of the Final Days progressively enroaching), and seems that it will remain for the forseeable future a novel one-off than the prototype for a new fleet of space exploring vessels.

It might be an interesting gameplay addition, but I just don't see it happening from a lore perspective.
