You could change the appearance of tenten for that of chun li from street fighter they are very similar the only difference is that she has good legs after all it is the same as tenten
you know you could.have tenten try and research other kunoichi that were powerhouses and stumble on the red devil(kushina) and learn she mostly fought with fuinjutsu and swordsman techs.... it would.fit her along her bukijutsu talent
