With COMP, I don't see any difference between Anthropic and Löbian-Thropic. With COMP, and via your UDA, our observed universe is selected from the set of all infinite strings (which I call descriptions in my book). Without the anthropic principle, ISTM that your theory would suffer the Occam catastrophe fate. How do you avoid that?
