Dear Nathan,

Not exactly the same, but see the code below. Note that the code does
not support creating CUSTOM_ID. Instead, it silently creates an ID if it
does not exist (see (org-id-get ... 'create)).
The helm completion will work if it is enabled globally. 

#+begin_src emacs-lisp
(defvar org-id-history nil
  "ID completion history for id: link type.")

(defvar org-id-cache nil
  "ID completion cache for id: link type.")

(defun org-id-prompt-id ()
  "Prompt for the id during completion of att-id: link."
  (let ((org-refile-history org-id-history)
        (org-refile-cache org-id-cache)
        (org-refile-target-verify-function nil))
    (let ((prompt-ans (org-refile-get-location "Select org entry")))
          (or (org-id-get (seq-find #'markerp
              (user-error "Cannot find ID of the entry: %s" prompt-ans))
        (setq org-id-history org-refile-history)
        (setq org-id-cache org-refile-cache)))))

(defun org-id-link-complete (&optional arg)
  "Completion function for id: link."
  (let* ((id (org-id-prompt-id)))
    (format "id:%s" id)))

(org-link-set-parameters "id" 
                         :complete #'org-id-link-complete)
