two group

This is my situation: -I have 5 nodes in 1 cluster. ( Node 1, Node 2, Node 3, Node 4, Node 5) 1-Now i want to migrate (Node 1 <-> Node 4, Node 2 <-> Node 3) if 1 node fail. Does it possible ? I know the priority is used but just 1 node or more 2 nodes with same priority, not the permanent one...
