I only use the golden room as a probable example of the process involved in creating the ultimate animata - i.e. Mog Pharau.
It fits with Akka's description of trapped souls being stripped of their experiential memories or "personality", leaving only that which can apprehend the logos.
The important thing I derive from this is that magical animata use a soul's ability to apprehend the logos to achieve the architect-sorcerer's objective; therefore said sorcerer must break or dominate the will of the soul that he wishes to bind.
Which leads to the inherent problem of using dunyain. I do feel that ability to perceive the logos would lead to potentially more powerful animata, however I think that using one of the few might yield more efficient results.
Tangentially, the dunyain pretty much strive to be 'living animata'. Beyond their mission, any "perfect" dunyain should follow the shortest path i.e. perceive the world as it truly is and thus see the onta, and act in a purely mechanical fashion according to the principles of logos.
Speculation: If Mog is viewed as a weapon of animata constructed from 144k broken souls and poised to upend the existing metaphysics of Earwa, perhaps Kellhus could be viewed as a weapon of animata constructed from a single unbreakable soul to oppose him.
