I tried something similar

My girlfriend was in heroic Gundrak, and since I hate that place, I stay as far as way from it as possible.
However, me being a rogue, the leather pants from the last boss in there seems nice.
Now, back to her again. She was in there, pew pews the boss etc, and of course they drop (typical) :>
She pressed Greed and actually won them. I tell her to try something, even though I know it's not going to work.
Then she writes a ticket, and BAM! She just had to delete them and I recieved them in my mail, nothing about raid IDs
Not sure if this has anything to do with it, but we made sure not the mention my name in her ticket, since we figured they might to some checking before actually answering the ticket :>
So, it might work. Depending on the GM I think

EDIT: This was EU, not sure if it makes any difference though.
