Please don't top-post.
If you do something like this, you will need to put your tablespaces in hot-backup mode. That only really works well if you can make a snap copy and can break off a mirror quickly, to get out of hot-backup mode quickly. YMMV.
I made a ghost copy restore procedure work once as a proof-of-concept, but I really felt it had way too many possiblities for manual screwups to be comfortable with it. Much better to do it the way Oracle has tried and trued. In a DR situation, you don't want a whole lot of thinking going on. Like "duh-oh, did I forget to put the database in hot-backup mode?"
As far as manually pulling out one disk drive at a time: http://groups.google.com/group/comp.databases.oracle.server/msg/1cedb062e0071ac0?dmode=source
