I would look up the blue moon clone thread and use that as a base. I believe it's 50% 2-row, 40% wheat, 10% oats. The one thing with Alaskan white is I think it has a strong fresh orange zest note. I would maybe use more fresh orange zest (no pith) at the end of the boil than the blue moon clone calls for. According to the website, here are some details.
Based on that, you may need a touch of light crystal to give a little more golden color, but just a little bit.
It's also really fruity, so their house yeast may be an English style as opposed to using Cali ale.
