Kagura specializes in kenjutsu and there is no evidence that he possessed hyouton. We don't know what chakra natures he has. But ofcourse, chakra nature aren't only inheritable in clans, but also single person can have their own unique kekkei genkai or kekkei genkai which is only inheritable by genes without connection with any clan (Mei, Kurotsuchi and Doudai lava release is good example of it. These three characters are from different coutries and no blood relation beetwen them but they same kekkei genkai vielders but in their own unique way). So everything is possible.
