Hi Sergio, There are many people more knowledgeable than I am on this topic, and I hope they contribute to this interesting question. My two cents would be to remember that the TSM database doesn't know about an array replication, so you'll have to deal with that issue if you have a massive recovery event. My other two cents are that to be certain sure that whichever solution you choose works as described. You can't test the alternatives enough.
