Yes. The way to make a binding not have an effect when a mode is
disabled is to bind it in the mode's map! (And you don't want to bind
C-S-' to hs-minor-mode-map but to the submap that C-c @ is bound to.)

    ;; C-S-' is C-" (on my keyboard).
    (define-key hs-minor-mode-map
      [?\C-\"]
      (lookup-key hs-minor-mode-map [?\C-c ?@]))
