That would be one big CNC router to mill a workbench flat on top!
If I were to have a CNC that big, I'd barely need a workbench. A flat surface for sanding/assembly the pieces would mostly suffice in most of the cases.
In any case, the "planing by router" is equivalent to building a CNC table/gantry then move the router by hand - the flatness of the surface will be as good as the stiffness of frame/bridge you build in this one-off fashion; if those two are stiff enough, you can use the same for a full DIY CNC build.
