iRule to load balance between 2 pools?

OK, the application servers (2 servers) do not support bonding / etherchannel but have two interfaces that can be configured in two different vlans so I'm trying to use bigip to achieve this using priority groups.

 

 

Since I don't want to have two IP addresses active on the same server, I can't add them all to the same pool and I need to have each server with it's 2 IP addresses in one pool and have each IP in it's own priority group.

 

 

Now I want RR load balancing between the pools using iRule and was not sure if this is possible
