If I understand your question correctly, you want to manipulate a deeply nested tree-like data structure, right? If that's correct, then perhaps a combination of clojure.zip and multimethods will suit your needs. Zippers provide a facility to transform (possibly) deeply nested immutable data structures in a way that "feels" like you are editing the data structure in place when you are actually not. To only manipulate the nodes that match a certain pattern, I would suggest writing a multimethod that allows you to identify a certain "class" of nodes that necessitate a type of modification. That way as you learn more about how your code needs to be structured to fit the needs of your data you can add new multimethod implementations to fit your needs. The default implementation should probably just move to the next loc in the zipper without modifying anything.
