Guna,
Just sharing my thoughts…
I understand from your initial post that, you want to use the feature of ‘multi instance queue manager’ of MQ 8.0. I was reading the below articles to understand how does that work…

[url]Using WebSphere MQ automatic client reconnection with the WebSphere MQ classes for JMS
This looks like a typical active/passive setup of MQ nodes, and both nodes points to the common storage and log files (similar to Broker active/passive setup with shared storage/SAN)
Is it possible to setup a VCS cluster that will redirect the requests to either of the node which is available and running? If that is possible, then you will get a single IP and PORT to which you need to establish the connectivity, which you can do so by using MQ Adapter 6.5 which is already supported to get connected to MQ 8.0.
Does it make sense to give this a try?
