If you want to serialize the data to EDN and back, and print them out into the EDN file as (keyword "arbitrary-char-sequence"), then using the normal Clojure functions for reading the EDN data in will leave those expressions as the lists (keyword "arbitrary-char-sequence"). Of course you could write a simple function that walks the data structure looking for such lists and replacing them with the corresponding keywords. However, that breaks round-tripability of the data if you ever have an occurrence of such a list in your original data before printing it to EDN. If you believe, or can somehow ensure, that will never happen, seems workable to me.
Using a custom data-reader like #my.namespace/keyword "arbitrary-char-sequence" with a globally unique namespace that you own would be less susceptible to such aliasing problems.
