What's wrong with scheme?
It has more emphasis on programming paradigms and Scheme is just a tool to convey them. Its core is small and simple enough that you could introduce advanced topics without the need for the reader to learn the language beforehand.
So perhaps a conceivable bonus is that SICP can somehow be merged with that book.
(This is not a direct answer to your question; there's nothing wrong with Scheme; just mentioning advantages of using Clojure.)
