Sure--this is exactly why $WikiLibDirs exists.  You have it right in
the statement:

It's not likely to be a problem.  You can also do

   $WikiLibDirs = array("somewhere/wiki.d",&$WikiDir,"$FarmD/wikilib.d");  #2


   $WikiLibDirs = array(&$WikiDir,"$FarmD/wikilib.d","somewhere/wiki.d");  #3

The first has the advantage that the pages in somewhere/wiki.d 
are truly read-only even for the other wikis.  You can also do either
of the above without overwriting the pmwiki setting, by doing:

   array_unshift($WikiLibDirs,"somewhere/wiki.d");   # same as #2 above
   array_push($WikiLibDirs,"somewhere/wiki.d");      # same as #3 above

I suppose--this just seems like overkill to me.  $WikiLibDirs really
has not changed much since I put it in (pmwiki-0.2!), and it has never 
changed in a way that would cause existing installations to break,
even with the scenario you pose above.

Ummm, you lost me on this one.
