Hah, that's very cool. I came up with this as an idea for a short story a couple of days ago (except slightly more drastically, as it involved the complete annihilation of humanity on a failure condition, allowing the practitioner to drag everyone else with him into his preferred outcome-world). I'm simultaneously pleased and displeased that someone's already given it a lot of thought.
