I'm a big clojure fan and not the biggest Lua fan, but I'm afraid you are mistaken. You won't find any dynamically typed language implementation that can come close to LuaJIT for the general use case.
What if you type hint everything in Clojure properly so all reflection is avoided? (does take some time, but with something like YourKit it'll be only a few hours max on a mid-size project)
If you're talking about raw performance, I'm afraid you're mistaken. If you're perhaps referring to the 'aesthetics' of the language syntax, that's pretty subjective, in which case you're right for your tastes.
