How were the Macondo's Axioms arrived at?
By listening? 
I would encourage you to read carefully the following page:

I am wondering why/what happens if channels are not positioned vertically. 
What does it do to the Sound? 

It relates to lateral resolution of human hearing. We have very high lateral resolution and very low vertical resolution, I do not remember exact numbers in time of angle by frequency but you might recognize it without numbers. Take a look at the configuration of human head - ears are located on right and left side creating base for horizontal space localization. The space localization is a delta between arrival time to right and left ear, so if the sound source is somewhere within horizontal plane then the aviving delta works. However, if the source is in vertical plane then the location of our ears not optimal to create a sufficient distance between the vertical receptors.  To have the same vertical resolution as we have horizontal resolution we would need to have one ear at chin and another atop of our head. BTW, if you observe the lives of the most sophisticated God’s creatures – Cats then you would see that Cats use “altered” space localization. When a Cheetah sits atop of a hill, observing her territory and see a pray then she try to estimate a distance to the play. Her ears are located atop of her head and very close – there is very little lateral bias and her vertical resolution is even smaller then humans. So, what the Pussy does – she tilt her head in side in order temporarily to increase vertical bias between her ears and to assess vertical distance (remember, she is atop of a hill) very precisely. Sometime dogs do it but they do it not because they are smart but because they try to imitate Cats.

You spoke above about the "minimum proximity" penalty. 
Does this affect only how far back the minimum distance for driver integration? 
Or other things as well? 

I do not think that if the drivers are match properly (according to their TTH characteristics) then it might affect others things. You also have top take under consideration though is that your MF drivers will be shooting behind the mouth of the upperbass horn and that MF driver will have much smaller horns. The whole idea shell be viewed from a perspective of vignetteing.
