Yes you could. But remember even hit pushes them back a bit, but I guess if you hit fast enough you could do some serious damage.If this was something of mine from a year ago, I'd be using it that way xD
Anyways, that could be used multiple times and drain out their chakra for example? Like if you used it 10 times they'd be reduced by 200 chakra? Also how does it push it out?
And, by the force of the hit, and by using lighting chakra; hitting the solar plexus being the weakest point of the body. The lighting chakra travels in from the point of entry to outside. The pressure of getting hit, and focusing your lighting chakra in such away pushes the chakra out.
Sorry if that makes like no sense, tired.
