I installed a cluster with different CentOS versions recently. What I did was installing SGE in each node according to its version, and sharing only the $SGE_ROOT/SGE_CELL folder.
This is mentioned in the documentation as a way to reduce NFS traffic: http://gridscheduler.sourceforge.net/howto/nfsreduce.html The only downside is that the nodes need extra setup on creation, but since that's a rare occurrence and there's binary packages available for CentOS, it's a good trade off to make.
