From what ive read on here, some folks have tried to install the sport bumper over the chrome bumper, with some small trimming modifications, with hit and miss results. I have a 04 SLT Sport and have read the actual bumper BEHIND the cover is different than the chrome one, either shape wise or something else. And to convert it to a Sport the RIGHT way, you would need to replace all the bumper stuff behind the cover with that from an actual Sport. Now again, i think with some small trimming modifications the Sport bumper cover will KINDA fit over the chrome one, but to me the work isnt worth not knowing for sure how it will look in the end.
