Perhaps the OP could do this?

#+BEGIN_SRC emacs-lisp
   (setq my-new-macros
 	'(("def" . "d $1 e $2 f")
 	  ("ghi" . "GHI only")))

   (defun add-my-macros (&rest x)
     (nconc org-macro-templates my-new-macros))

   (advice-add 'org-macro-initialize-templates :filter-return
 	      #'add-my-macros)


#+END_SRC

Admittedly, this invites problems if `my-new-macros' is malformed. But 
there could be ways to impose a discipline that would assure that it is 
not.


HTH,
