Is it possible for me to obtain these packs? I live in the U.S. and have a U.S. copy of the game. If I create a EURO PSN can I still download these? And will they work?

I have read that the extra ships aren't available for online use and I understand that, I would love to have the tracks for online though.

Is there any way for me to get these? Thanks in advance for any feed back!
