Sounds good however concerned it might be like mud flaps the don’t seat well and move around. The fit would have to be exemplary. Seat around the whole circumference of the bumper would have to perfect. Or the gaps would really be ugly. With drilling you can “pull” the seam together somewhat.

Well the edges use similar clips, but the frontal area of the lip uses bolts to tighten, albeit they are set further back so you can't tighten them up and pull the very front up very much compared to the drilled version.
