Yes, what you are trying to achieve may be done. I suggest that you take a look at the book "RMAN Recipes for Oracle Database 11g A Problem-Solution Approach" which applies to Oracle 10g also.

I posted a rather lengthy review for the above book on Amazon's site - I commented on the clone to a single host recipe in the review. The book is listed in Google's book library, although there are pages missing.

The other current RMAN book "Oracle Database 10g RMAN Backup and Recovery" makes the cloning process more difficult to follow than the Oracle documentation - that is just my personal opinion though.
