Cistron Telecom in .NL built a network exactly like that by placing the BBRASes (redback) close to the DSLAM, then encapsulating the traffic for each wholesale customer into a MPLS VPN using Juniper boxes. Unfortunately due to the bad investment climate and problems with (de-)regulation and the local monopolist Cistron Telecom doesn't exist anymore, and Cistron Internet is now a client of another wholesaler that indeed delivers DSL circuits over ATM to use in one central location (for the entire country!) Looking back I am still convinced we had it right but we were probably just way ahead of our time, alas.
