Interesting. I believe that kicks do have aplace in this area, but are limited by individual situations. It is unwise to perform many kicks whilst in a bar/pub/club for instance, but these may be effectual on the street.
One advantage Martial Artists have is that we are really in the minority. Thus when kicks are employed it can give an additional surprise.
The most effective strikes would be old faithful groin attacks using the knee or foot, in addtion to this is the blocking/striking of kicks with kicks. Moves similar to Ashi-buri, footsweep, can be employed ,along with mawashi-geri, but these must be practice techniques.
My air of warning is this, as soon as you lift your foot off the ground, you lose your own grounding. The higher the foot rises, the more unstable you become.
But, by God are they're effective you can pull them off!!!
