I don't think this is possible. Some slowdown will be inevitable. Also, if indeed the intent is to rewrite most of Emacs in this "lispy= " language, you'd need some non-Lisp (or at least non-subset) features, like complex data structures whose members are directly accessible. Otherwise, the translation will not be straightforward, and you get bugs (and most probably more slowdown).
