Please describe your use case, because I don't think I see why another
variable would be needed.  I guess you have INFOPATH defined (by
someone who is not you?), but you don't like its value or something?
It's not clear which problems you are trying to solve.

In general, I can say 2 things, which I'm sure you already know:

  . environment variables can be set inside Emacs
  . you can hack Info-directory-list in any number of ways, and do
    whatever you want with it, in Lisp

While the above two methods are not exactly what I'd suggest to an
Emacs an Info newbie, I definitely can see you using them.  So again,
I'm unsure what kind of awkwardness is bothering you.  Please
elaborate.
