You can keep the original function code in a variable. Use that variable
to define the global function first and later all modified versions of
it.
(defvar function-code (lambda (...) ...))
(setf (symbol-function 'modifiable-function) function-code)
I think it is better to keep your defuns static and make them call
other functions which are stored in a variable or other predefined
place.
(defvar modifiable-function (lambda (...) ...))
(defun static-function (...)
;; ...
(funcall modifiable-function ...)
;; ...
)
