Gas Wall Ovens: The House Project

The layout of our kitchen has a wall oven and a microwave oven, and cooktop in the island. I've run into an interesting problem: it seems that gas wall ovens come in a 24" wide size; if you want 30" wide, you need to go to an electric wall oven. I am a little concerned that a 24" wide wall oven won't be large enough for a turkey. We have a conventional electric range/oven combo right now, and a large turkey just barely fits. Is there something that I am missing?
