It should work just fine, you just have to understand what you're changing and what you're holding constant. Double the drivers = double the area. If we keep the layout of the horn the same, we have to change the width of the interior boards. If the board width is the only thing that changes, simply double it, then add another 1/2 inch for a brace.
Bracing is a very good idea with a 14.5" wide panel of 1/2 " material. Interior panels would be 15", exterior would be 16".
