I'm not sure if this would work as I haven't used it myself, and I play in 3rd person most of the time anyway, but maybe give this a try if you haven't already: http://www.tesnexus.com/downloads/file.php?id=21834 by kuertee
That's the one I bump into early in my search. Unfortunately, it's for adding triggered camera switches between 1st and 3rd person view, but doesn't prevent the vanilla forced view switches. Thank you for helping though, much appreciated.
