Bad idea. I've seen it done on a 2001-2004 tacoma and in my opinion, it looked ghetto. The only thing this will accomplish is pushing down more on the control arms and limiting your downtravel to just about zero. That it will ride stiff would be an understatement. Even worse, if its 4x4 and not prerunner, the axle cv's will bind. If you want 5" there's much better ways. If you're a prerunner, you can get the allied motorsports spindles for 4" then a coilover for another inch. If you're a 4x4, they advertise the pro comp lift as either 5" or 6" (not sure exactly what you do for the desired height). Even if you went w/ fabtech 6" you could use a coilover and crank it down to lessen the lift to the desired 5". I'm not a fan of body lifts at all, but if I had to I'd rather thrown in a 2 inch body lift w/ a 3 in suspension, rather than the spacer on top of hoes or camburg.
