Lower lip on nismo bumper broken

JKLiem

So recently the lower piece of the nismo bumper had received some damage, at first it was only one tab that had been ripped off but i had to go home. As soon as I get on the freeway i hear a flapping sound, so i pull over and take a look. it was the air moving the lower lip up and down. Now there are about 4 tabs broken. i would just get a new Lower facia but the actual tabs that it connects to on the bumper have broken off... I haven't been able to get under the car yet and look at whats going on but i was wondering can i just remove this lower lip piece completely? or would i have to replace the whole bumper...? Any help is much appreciated. Also would the Carbon Signal lip cover this part?
