There is no way to make the reach any shorter, short of inducing a comical level of wheel flop, and you can only make stack so low. Unless you resort to some much more advanced trickery (mounting the handlebar to the fork, for instance), this is really it. You can't make the front center much shorter or head tube smaller.
Personally I think the reach is fine. I'm 174cm, 81.5cm inseam and the smallest size would work for me, but I think I'm about the limit; any shorter and they're going to be compromises. A -17 90mm stem and I could duplicate my current position.
The lost opportunity is the seat tube angle. A steeper setup would make the necessary reach a lot more tolerable for a lot of people. It should be closer to 76 degrees, steeper in the larger sizes, just like XC bikes these days.
