Y-yes, that would probably work, erm, p-p-provided the cloth is thick and will resist the wind. A thinner cloth will let too much air t-through, and then t-the force of the wind will p-probably tear through it. It,um, n-needs to be sleek, too. Y-you need to make sure the wind can go over it, and, um, and under it without stopping. I-if it gets stopped, the pressure will build up in that spot, a-and that's dangerous. Anything that's n-not, uh, smooth risks snapping or ripping at higher speeds, o-or altitudes.
