The only concierge level rooms available to
DVC members on points are the ones that Slakk referred to at AKV and to the other non-DVC deluxe resorts (Polynesian, GF, YC, CR) that you can get on points. And these run in the neighborhood of 50+ points a night. A lot more than a two bedroom at some of the DVC resorts.
You cannot pay to add CL service to your villa. You could hire a person to live in the second bedroom (or a separate studio) and provide you with food and drink, but that would be a whole lot more.
