Yes!  This method works great.  The downside is you will have extra dishes to wash, but it is very quick.  To use the food processor to make pie dough, add in your flour, salt and Crisco (or cold, cubed butter) and pulse until you have pea-sized pieces.  Add in the water and pulse just until the dough comes together.  You can gently finish by hand, but be sure not to knead or overwork the dough.
