Good idea.  I tried the following code and it works well.

(defvar Info-mode-line-node-keymap
  (let ((map (make-sparse-keymap)))
    (define-key map [mode-line mouse-1] 'Info-prev)
    (define-key map [mode-line mouse-3] 'Info-next)
  "Keymap to put on the Info node name in the mode line.")

(defun Info-set-mode-line ()
  (setq mode-line-buffer-identification
        (nconc (propertized-buffer-identification "%b")
                 " ("
                 (if Info-current-file
                     (file-name-nondirectory Info-current-file)
                 ") "
                 (if Info-current-node
                     (propertize Info-current-node
                                 'face 'info-mode-line-node
                                 "mouse-1: previous node, mouse-3: next node"
                                 'mouse-face 'mode-line-highlight
                                 'local-map Info-mode-line-node-keymap)
