3 inch lift + 6 inch lift

So this is sort of a broad question and I have been looking around and not really found any information or research upon this subject at matter. I have a 3 inch lift on my access cab 2nd gen ( coilovers and aal's) and was looking at 6 inch lifts. I know they aren't the best and I know many don't recommend them but definitely better than a body lift. I don't plan on it and I haven't planned on installing one but if one were to add a 6 inch DB lift to their 2nd gen tacoma could they keep their 3 inch lift installed to achieve around a 9-inch overall lift? If so has anyone done this and have pictures? I just imagined since adding the drop bracket it pretty much puts the components on the truck at stock level again with the spacer and if I kept a 3 inch lift if I were to do this the cv angles would be just at the angles of a 3 inch lift? Let me know as I've searched and haven't found any topics on it! More information rather than opinions please =)
