Going with the 20px cell size.

The 10px cell test with a small number of iterations (1,000,000) is shown below. While the spires are reduced they are still present, especially at full resolution. In the scaled image below, the most noticeable one is to the left of the leftmost set of red benches.

I also tired using the 7px cell test (below) with very few iterations (top: 500,000 and bottom: 250,000) and larger max neighbourhood (30²) to reduce spires; unfortunately, the lack of training shows a lack of organization compared to the results documented in this post. So I’m going to stick with the previous 20px 5,000,000 training iteration version and spend some additional time working on the transition.
