There's not enough space. The iPhone 7 Taptic Engine (the only one I could find dimensions for on short notice) was .4 inches on it's smallest dimension. The new Magic Keyboard is .25 inches thick. I don't think it's worth doubling the thickness of the keyboard portion for the improvement the haptic version might give, it already takes the super thin iPad and basically doubles both it's thickness and weight.
