Let's see... Chōchō has Akimichi clan's Multi-Size Technique, which uses Yang Release, and she could potentially learn kenjutsu from Karui.

She could combine the two by having sword made of metal that channels chakra(like Azuma/Shikamaru's trench knives), and in battle she channels her Yang Release into blade(like Shikamaru channeled his Yin Release), enlarging the sword. And if she also learns Butterfly Mode, in that mode one possible attack could be called 蝶巨斬撃, Chōkyo Zangeki(Butterfly Giant Slash).
