Actually, we have internally talked about to move system VMs(secondary storage vm, console proxy vm, router vm, even the API server) to a separate service layer. CloudStack core will be an Orchestration layer, with lot of extension points, and manage above service VMs, also provide essential services(VM related, such as volume/network/VM etc.) to other services. In your case, IMHO, what you really need is a separate or customized way to create SSVM, CPVM in CloudStack, either these VMs can be running on bare mental hardware, or behind a Load Balancer.
