I'm not sure I understand your reasoning there. Not sure why you find stored outlines to be so costly/difficult - they're actually pretty simple and effective. Also not sure what either solution has to do with having to identify all the problematic SQL - that is something you should do regardless of how you decide tune/stabilize them. If your goal is stability, then why are you concerned about the plan being able to change with a stats update - seems like you'd want to test that in a test environment first and then update your stored outline if appropriate.
