Your recipe will not work as written. You have no base malt at all - nothing to convert the starches in the grains to sugars for fermentation. Torrified Barley has been heated to the point where all the diastatic enzymes have been denatured. Otherwise, it's a matter of taste - the hops and yeast you mentioned will make a beer. Next point: Crystal is completely out of place in a Pilsner, Pilsner's grain bill consists of nothing but malted barley. The bit of wheat could work to add some body. Another comment: Pilsner is a very demanding style to brew. I don't see enough of your process to know how you intend to mash, ferment cool, lager and so forth but I do see several errors that would push the beer out of the Pilsner style.
