Interesting read on the Miller cycle stuff. I've basically done just that with my new engine in order to gain both more HP and better MPG; cams are redone (VVT is no longer usable on my engine due to timing differences) and the static compression ratio has been raised greatly (from 9.5:1 to 12.5:1) while actual displacement has been lowered from 2.26 to 2.0.
Good to know I was on the right track, even if I didn't know the core logic behind it.
