As long as only one server is read-write on a given table, you're in
good shape.  Note that this four-by-four replication will require a
_lot_ of slon processes, so you're going to need to make sure you
have the horsepower for it.

You need one slon per database-target combination.  I'm not sure I'm
understanding your question correctly, but it sounds like you think
you need something like this:

Database <-> slon <-> slon <-> database

That's not how it works.  It's 

Database <-> slon <-> database
