There is actually a "Sweden Class" design which I originally imagined, and which MayhemUK was working on drawing. As far as I know he hasn't done any more to the drawing of the other views, and here's the only pic I have of it in "top view". The idea originally was suppose to be an "Advanced Intrepid Class" however that idea has since changed greatly. Size is suppose to be between that of the Intrepid and the Sovereign (4-500 meters), and be as technologically advanced as the Sovereign.
Would be fun to see if someone models this design, but having only the top view might be a bit limiting.
