Could LXD solve that problem?

Seems like having A/B containers in each of those machines would be
fine. The total amount of work isn't growing, it's just shifting from
one codebase to the next.

So, the three machines each get two containers, the Juju controller is
spread across three A controllers, the new one goes into the B
controllers, and migration essentially takes place on the same hardware.
