There is some solution to provide some form multihoming for IPv6:
3178 IPv6 Multihoming Support at Site Exit Routers. J. Hagino, H.
        Snyder. October 2001. (Format: TXT=24453 bytes) (Status:
        INFORMATIONAL

This solution is not very pretty, but you can keep the aggregation at 
Tier-1 and probably at Tier-2 porviders.
