No. That wouldn't work. What your not understanding is that the trophies are synced up to your account, and your account only.
Here is an example. Say player A has all the trophies for WAW. And player B has all of the trophies for GTA4. And player A and player B decide that they are going to share trophies. For that to work player A would have to give player B his account and player B would have to give player A his account. But then player A wouldn't have the original trophies that he had and player B wouldn't have the original trophies they had. All they would have accomplished was swapping accounts.
You can't just send your trophies to somebody else. It's not like they are a file that you can put on a flash drive and send to somebody.
