Hmm, the usual treeshaker might not tell you much about the internals of the compiler itself (a compiler is just one part of a Lisp system based on runtime, interpreter, various libraries, etc.), since the ones I've seen work over already compiled code. It's an interesting project, but not that easy for a complex piece of software like SBCL - depending on what the goals are.
