That's interesting and I guess it would have worked. Unfortunately the reality is that nobody assign people to tasks in purely community driven open source projects like emacs. People do the task they are interested in. At this point I guess it is more likely for elisp to slowly mutate into CL than emacs getting scheme support. I know very little of the lisp ecosystem (I barely can write some elisp) so I don't know what are the pros and cons of scheme vs CL.
