GMC Envoy

I have a 1986 gmc 3500 with single rear wheels. When i tore the rear brakes aprt, i found that i have the heavy duty versions, 13x3.5 shoes and drums. I would like to change the brakes over to the lighter version, 13x2.5 shoes and drums. Can i just swap out the old shoes and drums for the 13x2.5 versions?
