One relation per street, one relation per city, etc., with all streets as members in the corresponding city relation? I wasn't thinking of trying to force the address data into OSM format at all, but rather to store it away in a crude but persistent hash of a sort that mkgmap could learn to consult. Part of my reason for this is that I think the actual lookup of address data will be expensive, so you won't want to refresh these data as often as you will your planet extract - or at least, you'll want to confine you lookups to places that either aren't in your cache because they are new or that you have reason to suspect that a refresh is needed. If the hash is keyed on a combination of OSM ID and version, that could be the trigger for a fresh lookup from Nominatim or whatever service proves most useful.
