I wouldn't do it. There is too much geometry built into the straight axle such as castor, and camber, which will likely be altered by lifting it a "couple of inches". It will also throw your drag link out of wack.
Get yourself a set of LT215/85R16 tires. They will give you a noticeable lift. They measure 30 1/2" tall, compared to the 28" stock tires.
