How do you do this in the IPv6 world, where I get a single /32?  Will
others accept announcements of two /33s to better handle things like
this?

The better solution is to trade secondary services with some other
provider. Sure, it's a bit of a pain keeping up with the new zones
to be added and old zones to be removed back and forth, but, it's
a great way to have your authoritative servers truly diverse and
independent.
