CNC is CNC, if you can put an attachment on it, it'll probably work. If you replace the hotend with a router and make the extrusion wires turn the router on and off, you have a CNC router. If you use a swivel knife, you have a vinyl cutter

The Z-axis homing problem could be solved by adding a "pause" command (gcode M0, I reckon) at the very start.
The printer calibrates, pauses, you attach the pen, press continue, and it'll do the plot without zeroing the Z-axis again.
So does this mean if you give it a swivel knife it can also be a vinyl cutter?

Very nice! I used the same trick to make a PCB by making the printer use a marker to draw on the parts that I didn't want to etch:
