Multiple ORACLE_HOMEs in 9iRAC on Linux

We are building a Linux Cluster [initially 2 nodes, later 4 nodes] to hold multiple Oracle databases.

On Unix we always maintain seperate ORACLE_HOMEs if there is more than 1 database on a server
[seperate O_H allows seperate patching and seperate version upgrades].

On the Linux Cluster, we undertand, that there can only be 1 Oracle Cluster Manager install. Oracle's
notes on 9iRAC installatiion also include installing the Database RDBMS executables into the same
O_H as the Cluster Manager.

Would there be any reason why we can't have

1. One O_H for the Cluster Manager
2. A second O_H for the first Database
3. A third O_H for the second Database ?
