I like the idea, I am thinking of a lot of things in my head now as I type. A true to scale board made from three modular sections that can be fit together. I can see it possibly working, of course this would actually take some figuring out and some hands on trial and error in the garage or workshop, but I believe it could be done.
Each of the three sections had it's own motor, when assembled the sheet metal is covered with a one piece field cover to "tie" the three sections together for the purposes of allowing even vibration and to assure a smooth gapless transition between the three sections.
Just rambling as I type, I do believe it is possible.
As they say...
