Load balancing two hosts, multiply services, redundancy between those, but as single vs

I am faced with a LTM scenario, where I have Host A and Host B. Host A have services on port 1000, 1001 and 1002 Host B have services on port 1000, 1001 and 1002

From the clients perspective, it is not important which Host who provide the service, as long as it is able to reach a backend server.

What I have done, is create 3 Virtual Servers:

• vs_service_1000

  *   pool_service_1000
  
          *   node_Host_A:1000
  
          *   node_Host_B:1000
  

• vs_service_1001

  *   pool_service_1001
  
      *   node_Host_A:1001
  
      *   node_Host_B:1001
  

• vs_service_1002

  *   pool_service_1002
  
      *   node_Host_A:1002
  
      *   node_Host_B:1002
  

Each VS have the same ip. I have attached a tcp-half-open monitor on each of these pools, and I have the redundancy required. But it is not pretty.

Is there a way, to achieve the same redundancy using a single VS?
