The short answer is yes, but you have to find the one you want to swap with and work it out with them and through scheds. or the vacation guru. On the DALPA forum there is a Vacation Swap conference where you can post yours to see if anyone there is interested.

I'm not sure if there is a way to find out who has which week however so good luck finding them, maybe the vacation guru knows who has which weeks. I beileve that guru is Lynn Ivey, but call your CPO and ask who to call, might be different up north.
