I think that the effect will be addative if you think about it. you put on an underdriven crank pulley you are in effect speeding up the belt roation, you have pulled the weight closer to you. this in effect makes it seem like the accessory pullies have gotten large then stock and the crank pulley has remained the same, just as these pullies will be doing.

So if you put them together I think that the effect will be increased.

hope that helps
