Hi!

I'm not sure this is the answer you are looking for, but with Guix you
can simply install the desired "emacs-*" packages.

Should you install them to a non default profile, make sure you source
the relevant etc/profile or export EMACSLOADPATH to

$GUIX_PROFILE/share/emacs/26.3/lisp

(Replace 26.3 with your Emacs version.)

Once this is done, you should be able to call

  (require ...)

from your Emacs initialization file, or

  M-x load-library

interactively.

Cheers!
