Well, the compression ratio would end up around 12.3:1, which is pretty steep but nothing unrealistic for 93 octane pump gas. You'll just have to have good tuning.
As for the whole idea, I'm kind of up in the air about it. The Skunk2 stage 1 cams seem to fit well with the short stroke of the b16, but at the same time displacement is always good. For peak horsepower numbers the straight b16 route would most likely be better. The b18a crank will put a bit of a damper on your safe rev limit but should put you well over 1.8 liters of displacement and will offer a higher, flatter torque curve and more power down low.
