Um... been looking at the images and I don't really think that sliding the chairs is going to work, by far the easiest way to test chair/seat and controls feasability is to actually plonk a figure on a chair/seat and attempt to pose a hand on some of the controls.

That's what I did in testing my speeder, and thus discovered that there wasn't quite enough room for the legs to fit under the control surface without poking through the speeder's metal skin... lol!  Plus I needed to lower the seat's height, to get the knees underneath more realistically.

I think that you would discover a similar problem as all the control surfaces in your images seem to be supported by a continous barrier of support legs - ie no room for human legs to get under the 'desk'.  And without getting legs under the control surfaces, people couldn't reach control switches, or would have to sit sideways on - not really practical.

Just my opinion...
