Here is a video from the early 90's flying a traction kite from a kayak.
I didn't feel attacked, no worries!
Heeling force on kite boats is small, anyway, that is true.
For considerable upwind performance you will always need an effective way to redirect the wind generated (downwind) pull into something pointed upwind. This is possible through the hulls lateral resistance if it's long and slender(like in hobie cats e.g.), but done better by foils like keel or dagger boards. In my system I can (and do) use asymmetric hydrofoils, even more effective, I can do this because I have different foils for each tack.
