I have found that in thaiboxing a lot of people tend to be more square on than a boxer & when sparring with a boxer have had to take a more side on stance to cut down the amount of punches getting in though the front angles, although we just train at about a 45' angle to forwards to enable the use of kicks as apposed to the boxer who tucks in more as he doesn't have to worry or use his legs, i think what you mean by the kicking stance as the completly side on stance which i have only seen used in kickboxing & semi-contact point fights.
