I already addressed the knee part, so I can pretty much see the quill drive looks like a rack and pinion system. These typically have a LOT of backlash, and so are not a good choice for a live axis.
On Bridgeport-like machines, they have an adjustable stop contraption on the front of the head that exposes a threaded hole in the quill through a slot. This is a great place to attach a ballscrew drive and you remove the pinion. But, a picture of the vertical head on the 2B seems to indicate you don't have this kind of access the way the machine is built. I seriously doubt you can do milling work without locking the quill, which kind of defeats the purpose of having a controlled CNC axis. So, I'm not sure this is a viable option.
