Changing the switching on my ASAT Classic S

All,

I've decided to change the switching of my ASAT Classic S, specifically, when the push-pull knob is in the up position. Here is what I believe the current switching does:

1. Bridge+Neck
2. All 3
3. Bridge+Neck
4. All 3
5. Bridge + Neck

I'm changing this to:

1. All 3
2. Bridge+Neck in Series
3. Bridge + Neck
4. Bridge + Middle in Series
5. Middle + Neck in Series

The original layout essentially "wastes" 3 positions. I'm hoping this will allow me to obtain "humbucker-esqe" tones from my single coil guitar...
