nah, you can't maintain it even if its the same element. That's yin yang's ability mold chakra (whether its the same or different) to perform two jutsus at the same time.

Gin watches as the tornado helps the kid avoid the explosion and somehow at the same time the tornado stopped the lightning ball. He smirked, maybe he underestimated the kid. Gin bent down and touched his ankles but then rose back up thinking it wasn't time for that yet. The kunai is then thrown and Gin takes his lightning spear and focuses lightning into it. Then he swings the lightning spear 4 times at the direction of the kunai, the kunai is easily deflected and stopped. The 4 blades continue towards the kid, two in front and two making an arc and attacking from the left and the right.
