Expandable: yes, have done this for a mass-vhosting webserver in the
past.

As currently written, shouldn't work, since rewrites happen on *this*
message and since the message is never delivered, the bounce goes based
on the content of the real message.

If you inject the mail via SMTP, then using an SMTP-time rewrite should
fix it. 'S' flag. For the non-SMTP case, my first reaction is that
fixing the client is the only way, but I might be wrong. For PHP stuff,
it was fairly trivial for us to include a php_admin_value directive to
let the sender be set on a per-vhost basis:
php_admin_value mail.force_extra_parameters -fWHATEVER
