I really,*really* expect my CPE router*not* to remove global addresses from the LAN interface(s) when the link to the Internet goes down.

This depends. Will you have a static assignment? What will be the lifetime values issued by your ISP? Granted, You should be able to maintain them at least 2 hours, though in a multiple router scenario, I'm not sure how well they'll take to routing unpreferred prefixes.
ULA isn't a bad thing. It also doesn't interfere with your GUA. There's really no reason NOT to have ULA in CPE devices. If your DSL is down for a day or two, do you really want to worry about addressing? Do you want to connect to the Internet before you can have addressing?
