I'm not sure about configurations of lanes when using Tri-SLI and could be wrong. I just might not remembered correctly, but anyway it would be a little stupid if MB could not re-route lanes to be 16x-8x-8x and run @ 8x-8x-16x, when it has 32 for those 4 slots.. Why the fcuk would I need third card running @ 16x
However, this will probably stay a hypothetical discussion as you said, if someone doesn't step up with 3 VGA's to test.
I've always wondered why they don't give them all 16 physical lanes and then dynamically adjust them for best results.

However, if you look in slots two and four, you'll see that the pins only travel about half of the slot. Bummer
