I don't fully understand how you mean that.
But I guess it would become more complicated than just using multi instance.

I haven't found any postsrsd Howto with multi-instance. Everybody just
states that it rewrites everything and they don't care.
So what needs to be done to convert a single instance (handling
inbound mail on port 25 and SASL customer mail historically also on
25+587+465.) into multi-instance for SRS handling?
I have read the postfix MULTI_INSTANCE_README. Which instance would be
used for SASL, which for incoming "MX" mail and which for the SRS?
I think I have posted description of what I did here some time ago.
(in one installation I use vrfydmn after postsrs to rewrite From: as well).
Generally, I created separate instance for outgoing mail, route all mail to
that instance and rewrite sender in it.
This way sender gets rewritten only for outgoing mail, only when address is
not local.
This way, only outgoing mail gets processes in separate instance, and the
only setting you need to move there is transport_maps.
