In Kenichi, ki techniques aren't techniques by themselves, they're something advanced you can use to put power behind your attack and defense. You can not know a single martial arts move, and be a brilliant fight with using ki in your attacks, but if you're a master...
I don't think it works as well. I think plenty of masters, especially at the level of Ryozanpaku, can know a lot about ki techniques, but I think to say that it's a martial art form by itself is kind of off to me. Like saying a punch or a kick is its' own style, you know? If you're thinking about Odin or the Sagefist being people who used this 'martial arts', then it'd be mixed martial arts, as that's what they put their ki behind. I hope you get what I am saying. If you change it to another type of martial arts, that he can put the ki behind, then he is accepted. Mixed martial arts can't be one, just saying, because that's reserved for the Elder.

Also, guys, I'm going on vacation for a week and a half, and I don't know how much I will be able to reply, so...
If things slow down slightly for a little bit, that's why. XD
