Any1 swap. newer rear disks for older drums?

I have seen reference to it being done but no more than that. I have a /97 K2500, 7.4 lt 'burban (GM version actually, and wished I coulda found a bowtie at the time) and would be interested in maybe picking up a rear disk set from a newer model and putting them on mine. I would be interested in at least exploring this option if it even is an option. I would like to compare this option to going out and buying a new aftermarket kit. Is anyone able to shed a little light or direction to turn?

Thanks
John
