It's not the bumper falling that I'd have an issue with it would be the fitment issues you'd probably have.
My car when I sold it, with a standard 2000 front end, cut tabs on the 96 raddy support.
Cut tabs
Also forgot, inside top bolt hole on the 99-00 headlights will not line up either, but the inside (behind the grill), outer (behind the fender), and the top outer will line up.
Really up to you what trade off you go with. Personally, I didn't want to cut off the support and have the guy welding it back on to mess it up even a little bit. Honestly, if you're cutting it off, might as well just chop off the tabs first and bolt it together and see how you like it. Of course, if you're just awesome at maintaining structural integrity while cutting \ grinding \ welding, I say go to town. I knew I'd botch it though.
