CrossRoads:
So something like this then. 178mm wide, could be a little narrower, 50m tall.
Trying to hold to <200mm x 50mm for board size price break.
I do custom boards, custom shields.
What are you after besides the platform to mount stuff onto?
The pictures you have included seem like that shield would work great.
Rotating - sounds good, would make board really long. I think also less practical for power headers. Maybe just turn the outer ones?.
I could see making one of the three a arduino clone.Or at least alloeing for it to be populated as one.
How much of a task would it be to just use connections to connect one arduino pin to the corresponding ones on the shield slots? What is preventing that?

outer two is also an option. Think you should take 3 shields - with their connectors - and place them side by side, rotate and see how connections are affected. Eg. the ethernetshield has a big connector.
Most important is maybe to include some "slack space" as not all shield are the same size (esp display shields , screw shield)
maybe check http://shieldlist.org for the extra space needed to work with 90% of the shields.

WireJunky,
I got to thinking more about your question in #10 - I think you are asking how much trouble to put essentially a jumper space at each pin to let users wire each arduino signal to a slave header? I think that would be really useful, lets users only connect what is needed & avoids signal contention between shields.
Take a while to draw up.
So something like this - each header with a jumper pad to connect the header to an arduino signal, either the one adjacent to it, or to a different one. Only +3.3, +5, and Gnd are connected.

Need to get 8 Grounds connected up still before I could order cards (in February, after the China spring hioliday). You can almost make them out as black lines above.
It will connect if you put a wire between the inner hole at D10 to the middle hole.
A board with no jumpers would have no signal connected at the 3 sets of female headers, only +5, Gnd, and 3.3V.
Hmm, no 3.3V regulator. Maybe I should add one. 5V is expected to be supplied via 5V wallwart, 4.5V battery pack, or similar.

It's possible that 3 shields and the arduino will take more current than the arduino can supply through its regulator. I suggest a separate power jack with its own 1A 5V regulator might be needed.
