Is that like what the GCC-emacs project is doing with libgccjit? They are working (and have a great start on it) version of compiling most (all?) elisp with libgccjit to speed things up a bit if I understand it correctly. I have compiled it myself and it is most certainly faster to load and do "intensive" tasks faster than stock emacs. I've loaded both DoomEmacs and SpaceEmacs successfully with it.
