As a programming language aficionado, I get really excited by the idea of Guile-Emacs. Yet I couldn't agree more with what you just said. Breaking Emacs Lisp would be a disaster, evolving it slowly to add support for the desired features seems a much more reasonable choice. Not only on the side of package maintainers but also on emacs developer's: at least any effort is worthwhile, since it will be a little step of improvement on actual Emacs rather than starting or continuing a project which has more chance to be abandoned at some point than to merge into the main Emacs branch.
