    The hardware on my 2 node SQL cluster is over 5 years old and needs to be replaced. The cluster hosts 2 instances of SQL server csqlx\csqlx and csqly\csqly. Due to 3rd party software restrictions, I want to move csqly\csqly to its own separate 2 node cluster. This would allow me to upgrade csqlx\csqlx to Sql Server 2014.

    My thought was to add 4 new servers to the cluster.

    Remove the 2 older servers.

    This is feasible if you plan to use the same OS version.

    Then split the remaining 4 node cluster into 2 clusters each with 2 nodes.

    Is this possible? And what would the process of doing it look like?

    No, you'd need to evict 2 of the nodes and they would then not be members of any cluster. You'd have to form a new cluster with 2 of the nodes rather than joining all 4 to the existing cluster. Why split the cluster you can leave it as 1 x 4 node Windows cluster and that will be fine.
