FWIW, attached is simple POC code to do this.  It handles only
the Emacs and Elisp manuals, but it could be extended to other
GNU manuals.  (The main use case for me is that expressed above.)

Two commands, for use in Info:

`Info-url-for-node':  Prompts for a node name and returns a URL
                      to that node on line.  Interactively, it
                      copies the URL to the `kill-ring'.

`Info-goto-node-web': Prompts for a node name and goes to that
                      node on line.
