[neutron] Routing fake "floating IPs" of VMs running inside VMs of an OpenStack

I've been designing a CI for OCI  to make it more robust and easier
to contribute. After a week and a half, I've been able to make OCI
deploy itself in an OpenStack itself. OCI itself pops with a public IP I
can reach from the outside, and it setups OpenStack inside OpenStack VMs
on a flat, private subnet (currently 192.168.100.0/24).
This works pretty well, I have a fully working setup, and the deployment
is completely automated. This even works without admin credentials, so
all one needs, is a non-privileged account in any OpenStack.
However, at this point, I'd like to setup the network for VMs inside the
VMs. And that's where it becomes tricky. The VM that runs tempest will
need to reach the floating IPs of the VMs inside the VMs that are
running nova-compute, in order to do ssh tests. How can I do that? Is
this even possible?
