XEmacs Tried to do that, it has been attempted to rewrite the backend of emacs into Rust twice, Guile has tried to interpret emacs lisp twice. The biggest problem is basically how large the user base is and the ability of people to want to perform the port so actually improving the editor is more likely.

GTK+ and webkit has been integrated into emacs and it has a package manager now and configuration is still a problem.
