To satisfy this concern (about the JOIN command - which I really need to do before I start trying to make the necessary coding changes), I would really like to know if there is a mediawiki installation which currently used shared tables on one dd with the other tables of at least one of the wikis using this shared table being on an entirely separate db.

Mysql allows JOINing tables from different dbs. The problem I see with your setup is that I don't think you can join them if the user is not able to read both tables.
