That's exactly what I am suggesting, although my suggestions are not derived from speculation, rather solid and consistent data from tens of thousands of articles...if not more.
And at the end of the day when the competition filter, or whatever you want to call it, has done its job, you may only have one of those articles INDEXED, but your branding and direct traffic rates are so much higher than if you'd have only submitted one single article to one single site.
So far, Google has no problem with it. It's called syndication and I don't know why you would think it would be unnatural. Articles are syndicated every single day on a massive scale.
Using mass submission programs is spammy, syndicating an article to 20 or 30 different niche-related sites is not, IMO, of course.
