If you don't want to do a mini mash you could do something like this
instead. It is my extract IPA based on Jamil Zainasheff's "Hoppiness is an IPA."
You can take out the Cascade and put in Amarillo if you'd like to be closer to Yellow Snow. This Cascade recipe is ridiculously hoppy (cuz I like it that way) so feel free to tone it down a bit toward what you posted above. It might not taste like Yellow Snow but it should be pretty damn good. You could also use Rogue's Pacman yeast instead of the Safale Dry US-05 but I doubt you'd taste the difference.
