OK, good to know.  It would be good to incorporate
such an ability in an easy-to-specify/use manner.

E.g., in `help-fns+.el' you can just specify a list
of manuals to use, in a user-option.

It sounds like what you describe would need some
encapsulation, massaging, or interfacing, to let
users just do that to make use of specific manuals.
