VM public IP - but via network node

I have 3 controller/network nodes in HA mode. Floating IPs work perfectly. In addition I can create VMs directly on public/external network given that I add the external interface of the compute node as a port to br-ex.

This means that the compute node's external interface has access to the public/external network.

My question is whether it is possible to create a VM on the public/external network without doing so, but rather having this routed via the network/controller nodes. I know this is what would happen when using floating IPs, but I am specifically interested in having a VM with a public IP interface while not having an external interface configured on the compute host, thus -- via the network node.
