lol u cant 'touch' lightning if u got anywhere near where it was about to occur its path would be affected by your body, as you conduct better than air does. and even if kakashi managed to get to the lightning bolt while it was moving without it conduct through him instead, he would nvr be fast enough to catch or even touch it, electricity travels at 2x10^8 metres per second, 2 thirds the speed of light. the only reason you can see lightning is because the flash burns an image onto your retina, the actually transfer of charge between ground and cloud is over in something like a nanosecond (1x10^(-9)seconds), your eye can only take in 30 frames per second... think about it

so no, its not possible, and to even suggest it in the anime would be silly.
