Hello jbake,
LEM in most cases requires a custom connector to be able to read custom logs. LEM may not be able to parse your data now, but you can submit your request:
Submit a request to SolarWinds for a new LEM connector - SolarWinds Worldwide, LLC. Help and Support
I would contact Support and get them a sample of the logs and they can help you make a final determination on what is and isn't possible for your case. For the most part, LEM is the key player for Windows logs so that is your best bet.
