Need help : Bonding with separate Tx and Rx

Hi Friends,

Need help on the attached pic.

We have 4 nos 911 5 Hn Boards. we want to create a 150 Mb FD link from A to B. So i was planning to do bonding on RB 750 GL. But in Bonding if any individual link fails, all traffic shift on another link. But as per client requirement, if any of the link goes down then full connectivity should goes down. I dont know how to do this. One scenario is attached in the pic but i dont know how to separate RX and TX with 750 GL Router so that transmit and recieve will follow on separate links. Please help.
