Should be easy enough to do with a box kite, maybe with a diamond too, but most of the other types dance around too much and I can't imagine how you could keep the camera aimed at your subject with them. Box kite can lift a fairly good sized payload for its size, whatever its size is, and it also flies very steady. Another feature of the box kite is that it is, after all, a box, so it seems like getting the setup to work would simply be a matter of finding a way to secure your camera and then trial and error until it is aimed and focused right. About as difficult as securing a camera inside of any kind of box and aiming it right, which is much easier than trying to figure out how to secure a camera to a diamond shaped kite I'm sure.
