How to install 2 set of Oracle Clusterware into the same machines?

For some reason, we have to install another Oracle clusterware into the existing cluster.

1. we have 2 machines have installed oracle clusterware 10.2.0.4, but this clusterware is not running, the storage which contains OCR and Voting is not connected, but sometime we will connect it again, so we can't deinstall this clusterware.
2. we decide to use these 2 machines, we connect a new storage, and plan to install a new 10.2.0.5 clusterware using a new user account.
3. If sometime the old storage is back, we plan to shutdown the new clusterware stack and change some script and open the old clusterware.

Is it possible to implement? I know we can't running 2 oracle clusterware in the same cluster at the same time, but if one clusterware is not running, how about install and run the second one? If is possible, How many scripts or files need to be backuped to ensure the old clusterware not broken? like /etc/init.d/init.crs, init.crsd, init.cssd, init.evmd ?

Any suggestion will be very appreciated.
