32 channels is too shy for monitor console for at least 2 reasons:
1 - A short channel count immediately flags you as a penny-pinching upstart.
2 - The dropped channels will cause a patching mistake when you least need it - crunch time.
Additionally, as convenient for you coax or fiber or Cat5e may be, the artists, promoters, audiences do not give a rats tail how consoles are connected - copper, cat, garden hose. Have 2 modern fullboat consoles at FOH and MON, preferably same brands that can share a single spare PSU if needed.
