Yes that would be possible by parsing logs (should be simpler than parsing leases). Probably better not to reload unbound, you'll lose cache - to avoid that you can use unbound-control's "local_data" and "local_data_remove" commands, or you can write to a local zone file served by NSD and point unbound at that.
