You don't really need to do that. Simply using the syntax table should
be sufficient in this case :
(with-syntax-table emacs-lisp-mode-syntax-table
(save-excursion
(goto-char (point-min))
(while (re-search-forward "[0-9]" nil t )
(let ((bounds (bounds-of-thing-at-point 'sexp))
(number (number-at-point)))
(when number
(delete-region (car bounds) (cdr bounds))
(insert (format "%s" number)))))))
