Change pulley ratio?

I know I'm a little late to this, but I was thinking about this the other day and was wondering if one could simply change the size of the pulleys on the hydraulic power steering pump. I'm not familiar with them to know whether they work on speed or force, but I assume either halving or doubling the circumferance of the pulley would halve the power and therefore halve the load on the engine. I personally have a 4000 lb truck and it is not the easiest to steer while eocing even at speed(30mph), so I don't want to get rid of power steering completely, but I also don't need it's entire capacity.
