You probably could but I'm willing to bet they'd charge you the package price anyway. Have you called Fairy Tale Weddings Yet? A few months back I inquired (actually had the pavilion booked. Here are the prices....add-on packages start at $2,100 and include your limo, the ceremony (at WL, Sunset Cove, Gazebo at the Y&B or Boardwalk), cake & champagne reception, and your flowers (for you and hubby). If you opt for the wedding pavilion the add-on package is $2,900.
Another alternative is to contact Jane at Gifts of a Lifetime. This was posted a few weeks ago and if you do a search on this forum you'll find some additional info on Jane and what she can do at WDW.
Have a great trip and good luck!
