I've been working on that as part of https://bro-tracker.atlassian.net/browse/BIT-1521
There's a bug in the current known services policy that causes multiple protocols on the same port to not be logged to known_services.log, but they should still show up in conn.log as the proper service.
There is a slightly different but related issue in that if you send an http request to an ssh server or an ssh client banner to an http server, bro won't attach both analyzers to the connection. So, you'll get either an http log or an ssh log, but not both.
