Can The ASM Disk Header and Disk Group Be Renamed?

I have a requirement to mount multiple SAN clones (EMC Symclone) of a production ASM instance on the same development server. RMAN is too slow to be an option, unless I find a white paper explaining any way to make RMAN perform a clone faster than the SAN.
The default response is normally, "Do your clone to dedicated hardware." However, that answer is not an option for obvious financial reasons, especially since I am working with a RAC environment with ~10 development and test environments.
The only way to do this (that I can think of) is to rename the disk header and probably the disk group prior to making it available to the ASM instance.
I have heard that Oracle has come up with an undocumented solution for one or more businesses. I believe it has something to do with the kfed library located in $ORACLE_HOME/rdbms/lib.
Has anyone out there managed to do this? If so, can you share your solution or point me in the right direction?
I know I am not the only one out there looking for a solution to this issue...
Thanks in advance.
