This is a good idea. The other advantage of using the drogue is that it
will keep the kayak pointed in the same direction, so your image will be
more stable when recording in stereo. It would be very cumbersome to
use in a kayak, but if you want to experiment before buying or making
anything, the old fisherman's trick is to just drag a plastic
five-gallon bucket.
If you do try it, I'd be curious if the line between the drogue and the
boat makes noise.
