I think you are confusing a number of things..

peer-to-peer replication is not typically used in cluster configurations because the database files are on shared storage and onyl one server may be in control of the shared storage at a time.

It sounds like you are talking about a multi-site cluster which has some challenges.. If that is it you might look at:

Clustering is not a load balancing solution, only one node will be used for an instance of SQL, on failover the other node is used.

Perhaps you should lay out what your goals are for this setup.
