@BryonyRae Thoughts on this? Clearly I've adapted it somewhat, but this is essentially what I had in mind when thinking it would be somewhat easy to do this on multiple floors. I've preserved all the lines as in the original roof, but incorporated it into the third floor, and used the decorative dome piece to get around needing another full story for the uppermost right angles. I'm actually thinking of a much more complicated version right now which wouldn't need the dome piece at all, but I wanted to show this to you first.
