This problem exists today.  If I need public IP addresses at a smaller
remote office (VPN Citrix whatever), I either have to get them from one
ISP, the other, do some weird multiple IP's on a host with source routing
thing, or BGP.

Isn't BGP traditionally the solution for multi-homing/redundancy?  At which
point you have two options:
1. the IPv6 routing table is small ~256k routes, so just take a full table
2. use a prefix length filter appropriate for your given situation

Routers that can handle multiple 256k route tables are not expensive if
you're willing to live with something other than the big players at a
branch office.
