What I dont understand is the need to stay 1:1 routable. Most all of you larger ISP's could have your own private IP Space by simply running a NAT'd infrastructure. Why not do it for all your customers?
And what if you want to host a webserver or mailserver? Why stop there, what about with local exchanges in the PSTN, you could put all towns on their own extension based PBX and save time in having to allocate phone numbers.. Steve

RFC2373 site-local addresses assign a /48, with 16 bits of subnet ID and 64 bits of host ID. The average location probably doesn't have 2**16 extranets on one DMZ; picking a random value usually yields one that nobody you're talking to is also talking to, so almost nobody needs to use NAT for this kind of thing, assuming you plan to tunnel them.
