Use the right tool for the right job.
Use smtp_generic_maps on the network boundary, to transform addresses
that are valid only inside the network, into addresses that are
valid outside the network, without exceptions.
Use aliases on the network boundary MTA, to route mail that enters
the network from outside, to whatever addresses you use internally.
