As I said, this is generally impossible.

But what happens in reality is either the stomping or the manual is
renamed into emacs-xx, to allow several versions of manuals coexist.

I suggest to look at a typical Debian system with several Emacs
versions installed, and see what kind of arrangement they use.  At the
time, this was one of the reasons for the complexity.  Maybe it no
longer exists, I don't know.

In any case, the problem with being able to control where Emacs looks
for the misc manuals still exists, for those Emacs packages that are
developed and distributed separately.
