I guess not, as there's no way to individually reject or defer
recipients with not_smtp.

Sorry, I still don't understand why you need such a flag or what your
transport filter is for. If all it does is adding additional recipients,
you could do that in a redirect router with "data = ${run...}".

If you want to prevent duplicates with an external programm, you have to
check the whole recipient list (which is available in $recipients, but
not generally, so you may have to save it to acl_m_recipients in
acl_(smtp_data|not_smtp), but beware of bcc disclosure).
