Dining plans are based on check in date so you would not be able to get next year's plan with a 2016 check in date.
To get the 2017 dining plan you will have to do 2 separate resort reservations. The first would be for one night (checking in on 12/31 and checking out on 1/1). The second package reservation would be for Jan 1, 2017 through the end of your stay and would include the 2017 dining plan.
You could do the one night (12/31) as a room only reservation and pay out of pocket for food for that one day. If you book the exact same resort and room category for both you could note it is a continuing reservation and request to remain in the same room. While it is not guaranteed, the room assigners will do their best.
