Have to start your search somewhere. Watch out for an older distinguished-looking gentleman giving proper tours, not the fellows that accost you at the exit of the bus/train station with a few simple sentences.
If I was a researcher with no travel budget I'd try cross referencing a list of medium-small touristy towns (like Cusco) with decades that had upticks in tourism and a very bad local economy. Narrow it down to above-average income college grads and start asking them if they are or know of a polyglot. Can probably get pretty far with nothing but Facebook.
Just a guess, maybe I'm wrong about this pattern. Let me know what you find out. ;)
Edit: I was also intrigued by your comment until I read "in the same way older immigrants have broken language" - this is indeed the common but rather narrow experience. I don't think I'll be able to convince you of anything. Best assume you are corresponding with the Loch ness monster.
