I don't think its quite as simple as that Ron. If the role of a service provider is to provide service to its customers then an ISP with a LISP interface may advertise the entire LISP prefix to its global unicast non-LISP customers, but no further. This is in addition to your consideration that the ISP would conventionally want to advertise the specific LISP prefixes of its customers to the larger inter-domain routing space. This is comparable to conventional routing theology: you advertise default to your customers and advertise your customers' specific routes to the world at large.
We tried this with a similar experiment with 2002::/16 some years back. It was not a blinding success, but maybe there are lessons to be learnt from that experience.
