Sorry Doug, I couldn't complete that train of thought - so, others may disagree, but there are several reasons why I would avoid this way:
To short the DC, you have to somehow disconnect, or block the battery, otherwise your shorting not just the turbine but also the battery. This needs to happen reliably every time or you could have an unloaded turbine, or smoke where it doesn't belong.
I'd also be concerned that you might damage the rectifier. Although I can't speak to this from experience, there location in this case is such that I wouldn't want to take the chance.
Generally switching DC is more problematic, particularly the "opening" piece if there are high wind shutdowns involved. If it is just a parking brake, this may not be a concern.
