Load balancing SMPP authentication with MRF and no iRules. Can it be done?

Thus far this is the algorithm I've come up with;

Code
When request from ESME;
    Is it a bind transmit from ESME
        Yes
            Send to both pool members
        else
            Is it an unbind
                Send to both pool members
            else //assuming all other messages are submit_sm related
                Load balance to either member   

Hopefully I'm on the right track here
