Seems to me like the more powerful awakened beings have a good idea of how yoma, awakened beings, claymores, and the world around them all work. Not to mention the beings in the areas the organization doesn't control have free rein to do whatever they want to whoever they want.

I imagine they could do their own organization-like experiments... if that's what you're getting at. I don't think they would though. Easier and more entertaining to get ordinary claymores to awaken and decide if they're keepers or not than it is to turn ordinary people into pseudo-claymores, train and nurture them, then get them to awaken and decide if they're keepers or not.
