[syslog-ng] eStreamer src Integration

Has anyone looked at sending Cisco eStreamer events to syslog-ng ? We have a couple Cisco Firepower management centers and I would rather use syslog-ng over sending directly to splunk so that we may use other integrations like elastic and our NMS. I have the eStreamer SDK on my syslog-ng server and wondered if anyone else has worked on this. Search of the user archive says no. Thanks Scot
