Before you answer that question, settle in your mind what you can achieve with planting wheat or going to corn. If your area is historically short of moisture at the critical pollination stage and grain fill, corn won't get you to the pot of gold at the end of the rainbow. If you are in a growing region where you can raise high yielding durum or other wheat, you have a shot at it, perhaps. If weather patterns give you the privilege of planting either with good odds of success, it's a great option.
If you were to ask this question ten years into the future, with better wheat genetics, I would love to say, by all means, plant more wheat.
