I don't think it's a good idea to use typology as It may not be scalable for big deliveries.
Easiest way is to create a workflow (scheduled or use post process in external account), collect new broadlogs and update your table 'cus:unsub' .
You can also do it in your campaign workflow in case you don't have lot of campaigns to update
Thanks,
