Another way of doing that:
(def data {:b--name "B", :a--id 1, :b--id 2, :a--name "A"})
(defn transform [data delimiter]
(reduce (fn [acc [k v]]
(let [[f-k s-k] (-> k (name) (str/split delimiter))]
(assoc-in acc [(keyword f-k) (keyword s-k)] v))) {} s))
(transform data #"--") ;; {:a {:name "A", :id 1}, :b {:id 2, :name "B"}}
