2 spindles 1 inverter

Opinions wanted!

I am adding a second Colombo spindle to my router.This will give me
two 5hp/same amps/volts etc. spindles. Given that CncPro has only 4
IOs I would like to use some contacts [normally closed] at the home
position of each Z.
IE: when a spindle is up to it's home position the contacts open and
cut power to that spindle.When either spindle moves down to work the
contacts close and power up only that spindle.
The desired result is that I can turn either spindle on or off with
M03/M05.
The alternative to this is to use two of the IOs and two inverters
[probably safer] but a real power hog at 30amps per inverter on single
phase,plus my vacuum pump is pulling 20amps,

thanks
Carl
