An alternative is to use --init-directory with thin wrapper around your normal config, e.g.,
you can create arbitrary configuration which makes small tweaks to your
normal configuration with something like the following:

$ cat /tmp/e1/early-init.el
(add-to-list 'load-path "/path/to/org")
(setq user-emacs-directory "~/.emacs.d/")
(load-library (expand-file-name "early-init.el" user-emacs-directory))

$ cat /tmp/e1/init.el
(load-library (expand-file-name "init.el" user-emacs-directory))

$ emacs --init-directory /tmp/e1
