I agree w/ K Gopalakrishnan, running more than one version of clusterware, while it may be technically possible, sounds like a really bad idea. Clusterware can be rolling upgraded, and newer versions of clusterware will support older versions of ASM database. I currently have 11g CRS, 11g ASM running on a cluster with both 10g and 11g RAC databases running, with no issues.
I can't think of any reason to run two versions of CRS on the same cluster.
Hope that helps,
-Mark

Do you have any specific requirments for running this config.. perhaps we can suggest some workarounds (!)
