If you to do it right you will have to change out the front bumper, headlights and hood. I am in the process of changing my Red 97 to the 02 headlights and we actually have to cut out the rear bracket behind the headlight to make the new ones fit. I am assuming you will have to fabricate some small supports to hold the pop ups in the bigger space your headlights currently occupy. As for cost I would be willing to bet you could get it done for free. Just find someone who has a pre-02 car and offer to swap the necessary parts as long as they pay the labor to have the pop headlights installed in your car. The other option is to buy all the parts necessary for the conversion and then keep your originals so when you sell your car in the future you put it back to it's factory setup. BTW if you decide to buy parts I can make you a package deal on a 97 Red front bumper, headlights, and hood.
