In our KVM deployment we've found mapping 2 floating IPs to an instance (pulled from 2 separate external network floating IP pools) like this is perfectly possible, with the proviso that with port security enabled on the Neutron ports static routes must be placed on the instance to ensure that traffic uses the correct interface, i.e. return traffic that came in on the private interface associated with one floating IP must go out the same interface and not another (or it will likely be dropped at the hypervisor).
