Don't know if this works, but I know that you can transfer no trade items by dropping them in the guild hall as the guild leader.. then starting a vote for whoever needs the items.. they win vote, they get guild leader, and can pick up the no trade items....
So theoretically it should work but it seems like a lot to test.
Even if it did work, the quest to replace the Elder Robe makes you turn in your old Elder Robe....chances of someone just giving it away is slim at best. I know I wouldn't lol
