I'll be interested to see how this goes as I have a Warco VMC myself that is on the list for a CNC conversion. There was an earlier thread on converting a VMC but that was a few years ago and technology and components have moved on a bit since then, maybe. Certainly the x and y slides move easily with the handwheels but the z is pretty heavy if you are driving the knee (although it doesn't need the same feed speeds, I guess, unless you are into 3D milling, so could be geared down somewhat).
