High Availability CARP between two ISPs

I noticed with the above diagram, the WAN links between the two firewalls are both on the same subnet, so it appears to be one ISP. What if you have two PFSense VM Instances running, one VM with a static WAN IP from Integra, another VM with a static WAN IP of Comcast?
You would need at least 3 public IP addresses on each WAN to do it right.
There is not much difference where Multi-WAN is concerned when you go to HA.
Discussed in some detail (gold or book required) here: https://portal.pfsense.org/docs/book/highavailability/multi-wan-with-ha.html
