Pretty nice speculation, bxr. But for now let's go with what the Bitubo engineers say. After all, they built 'em! Besides, it's easy to see that they started out with stock F800GS forks. They're just blueish colored now because of the coating they applied. Also, it's speculation at this point how they actually achieved 60mm more travel. All I'm seeing them say is that there's more travel, not more height. There's a big difference between travel and ride height. And it's speculation to say that dropping the sliders 60mm (which they didn't actually say they did) would weaken anything.
