Maybe you can just redefine the struct in your personal
code. Redefining seems to work as expected. For example, here I
define a struct with slot "sex", then redefine it with "slot"
"replaced" with "gender":

    ;; -*- lexical-binding: t; -*-
    (require 'cl-lib)

    (cl-defstruct person first-name age sex)
    ;; => person

    (mapcar #'cl--slot-descriptor-name
            (cl--struct-class-slots
             (plist-get (symbol-plist 'person) 'cl--class)))
    ;; => (first-name age sex)

    (cl-defstruct person first-name age gender)
    ;; => person

    (mapcar #'cl--slot-descriptor-name
            (cl--struct-class-slots
             (plist-get (symbol-plist 'person) 'cl--class)))
    ;; => (first-name age gender)
