When you have 16 in a square and you want to transit to a diamond, that could look quite nice.
I doubt transitioning from a square to a diamond is reasonably possible with 100 considering the given length of lines at 120 feet. The diamond itself is the problem being that the upper tip would most likely be well outside the wind window.
I picture two reasonable ways to transit at this time. One being a slow rotate of all revs in clock fashion by 45 degrees.
The other is kind of a breath in breath out method where sides breath out and the corners breath in.
I like the latter best.
