2000 Envoy headlight conversion

Does anyone have any info or knowledge of the poss. or feasability of converting the headlights on a 2000 envoy. I need to change from the High Intensity (and Hi-cost) xenon, back to the regular halogen bulbs. Is there a kit already avail. to do this or do I need to swap parts with say a blazer/yukon setup. Thanks for the help.....
