I have a small parafoil kite that I take backpacking along with a spool of spiderwire. A tail on that would attract a bunch more attention, flies much higher, be much less energy to use and could be launched, tied off to a tree and ignored whilst I made dinner with the sling-shot out of some of the local rodents. The kite is lighter by a factor of 10 even with the spiderwire and streamer. BTW, I would use some mylar as the streamer rather than hazard banner tape. Mylar is lighter and at kite heights might even attract radar attention because it is radar reflective. Make sure you get the strongest spiderwire if you intend on getting any real height on the kite. It will amaze you how hard the high altitudes winds will tug on that kite!

If anyone knows where I could get a decently strong mylar parafoil (frameless) kite that would fit in my shirt pocket along with a couple hundred feet of spiderwire I would be very interested!
