Here is a Nature paper on brown dwarfs and X-ray emission. A quote from that paper:

So I guess this sort of throws my idea into the waste basket.

You think so?
Considering how we don't fully understand these pulsar-like BDs I wouldn't throw out your idea based on their expectations.
A more recent paper,
here, discusses BDs as well as UCDs (ultra cool dwarfs) and their sporadic long term variability, favoring ecmaser emissions as the more likely mechanism. However, and as the authors say, much more data is needed before anything which regards their emission mechanism or long term variablility is certain.
What's your take on this "quiescent" aspect of BDs / UCDs and might it affect your idea?
