I don't know about the light wheat, but use the rest of the grain. As far as hops go, I'd go something like this:
FW - 1/2 oz chinook, simcoe, and centennial
0 minute/hopstand(30-45 min) - 3 oz El Dorado
I think that would stretch your hop bitterness/flavor/aroma the furthest. I don't think it will be quite an IPA, but it would be APAish
