Maybe this experiment could interest you (clojurescript as a plugin of gnome): https://github.com/technomancy/lein-gnome
In general, if AFAIK the main performance issue is the jvm startup time and the loading of the clojure.core library, one first solution could be keeping a single background repl process active, which could run in separated threads every shell script feed to it via a tcp socket. Every thread should live in a isolated sandbox in order to keep clean the overall environment.
