As bove would be pretty easy, depends how nuts you want to go, I personally would unpick all of the radiator support and it's skirting to just leave the rails and the side's of the bay showing, clean up all of the edges, then make tabs at the top on either side for the new support bar to bolt to, then make the bar out of whatever you desire, the mounts wouldn't be too hard, the headlights half mount off of the guards anyway
