Instead, get rid of the fake side air intake and give it an air dam.
My understanding from aerohead is that 30* is for the spoiler, but the rear window exceeding 22/23* is the max for attached flow, and that even that would need a longer lead-in curve than production cars can accomplish. The ideal is still about 15* from what I have seen (the "template" and the "Prius"). That's just my understanding, if I understood aerohead correctly. Winkosmosis, you think that's incorrect? But I agree on the side intake and the airdam, of course.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
