Can I use an HDMI cable for a control pendant?

I'm putting together a pendant control for a CNC machine, and need about 14 conductors. I can get inexpensive HDMI female screw terminal breakout boards and a 6' HDMI cable would be perfect form for this application. The wires are for x/y/z axis selection, movement resolution (x1, x10, x100) and a manual pulse generator encoder with +5v,0v A and B. I'd use 24ga wires from the breakout board to the controller connector. Any reason this will not work?

Google says cheap cables use 30 or 32. A good cable should be 26 or 28 if only a short length.
I certainly would not use a cheap cable.
