As long as both sides of the cluster would run the same version for the same database, yes. Of course you are aware 8.1.7.4 has been desupported.
And our experiences with Suncluster are very negative, in as much we are going to dump this product as much as we can. The overhead is huge (the suncluster monitors are constantly connecting to each database), the administration is a nightmare (you''ll need a separate listener and tcp/ip port for every instance) and Suncluster just fails over the databases randomly, ie as soon as there seems to be no response within a certain amount of short time.

If you have 'a number of 8.1.7.4 databases' and 'a number of 9.2.0.6' databases running, you are already up to something you really shouldn't do, and in your cases Suncluster will probably help you to pull your hair out. In our case we have only 2-3 instances per server, and Suncluster can't deal with this.
