I have limited knowledge of OpenStack, but I host many servers with 
Hetzner and know their infrastructure well.

Since nova allows you to assign specific floating IPs to specific 
instances you could do the following.
Create a floating range include all of the IPs Hetzner has given you.
Then just associate the IP from the underlying host with a VM running on 
it that host using euca-associate-address.
