There is nothing to say that it can't be done. I believe what you are describing is the driving force behind http://www.ownertrades.com That website was born on the concept of owner to owner trades. So perhaps you can check out that website and see if anybody has a Maui week they are interested in swapping that would work for your needs, and in turn, you could either provide points for your value in the swap, or book a week they would desire with your points. Can't hurt to try.
