There is no reason that all the motors and drives need to be the same.
You could even use a stepper on the X. It would be a strange thing to
do, but it would work.

You probably want to run the spindle off of a VFD anyway, so you can
use a single-phase input inverter to drive the 3-phase motor.
It is possible that the current drive can work off of single phase,
possibly with some derate.
