Your requirements appear to be contradictary, on the one hand you
want routing sensibly based on recipient domains, on the other hand
you want routing based on the client IP. Which is it? Describe
more clearly what you expect to happen.
You may find that the recent additions to Postfix 2.7 (IIRC)
sender_dependent_default_transport_maps
sender_dependent_relayhost_maps
helpful. Most likely your requirements are solved by deploying
separate Postfix instances:

trying to hack context dependent routing into a single instance is
unnecessarily complex and fragile.
