That's the first thing that crossed my mind when I saw this project but I think it might be a mistake. Convincing people (and contributors) to ditch C-emacs for "remacs" will be hard, convincing people to ditch elisp-emacs for guilemacs will be hard but doing both at the same time might be just too much. If remacs manages to reach the point where you can use it to replace emacs in-place without any breakage while bringing better performance and more stability it will be a tremendous success IMO.
