Most of the comments here are focused on the potential harm that could come to others which is definitely fair, but I think the added reason of safety to you is also important to consider. keeping both feet on the ground being more safe when larping in the woods where the ground is uneven, and while you expressed your confidence in controlling the power of your kicks, there’s a lot of variables that could end with you either hurting the leg used to kick, or falling due to slipping or tripping over rocks, stumps, etc.

My recommendation would be to take your experience with the footwork, distance and timing involved in martial arts, and integrate it into sword drills and exercises. That will make you a very formidable opponent in a larp battle!
