You've probably gotten nearly all of the performance you're going to get out of it without resorting to mutability, perhaps by threading a StringBuilder instance through the whole affair, or at least accumulating not a string (via a sequence of "str" calls) but a coll and doing a big "apply str" over that at the base case: (assoc a (apply str ks) m), which amounts to the same thing (should end up using a single StringBuilder under the hood to assemble the entire string in one pass, without creating a temporary String object at each intermediate level).
