Quick ? about the H4 headlight upgrade - ground circuit.

When converting to a basic H4 headlight, is it okay to run a separate ground wire for those head lights ? Originally, I think Chrysler had the drivers side marker pigtailed to the left headlight, pigtailed to the left parking light, than to the right side in reverse order, with a black ground wire travelling back to radiator support, in front of the battery. Can I run the same circuit minus the headlights, and than back to the negative battery ground, and a second stand alone headlight circuit with a bigger ground wire running to the negative battery ? I'm running 14 gauge for the new headlights, and it's easier to unplug the headlights, strip, tin, and solder the blacks, rather than to create a whole new ground circuit, and soldering in side markers, and parking lights. I need the upgrade in headlights to see better at night here in the mountains, not for the cool modern factory. Thanks
