sounds really neat, i would try using a lisp that is closer to the metal though, something like microlisp or, my favorite: janet
coupling clojure with python sounds like a drag, even using graal i dont think this will be easy. but janet you could bind as a dll and eat your cake while having it as just recently FFI was added. if you are interested, i can probably help a little as im working on an integrated (game)development repl myself. not sure how to classify what im working on but i think its close to your domain as i want to change my hotloop during runtime from the repl and from inside the running game. i just wrote you an email.
EDIT:
ah, just now read that you want to make this a webapp, in that case being closer to the metal isnt really helping, so nevermind ^^
