Can MESA work without LinuxCNC?

Hallo,
I would like to ask if it is possible to use MESA cards without LinuxCNC? I am thinking to use it to control hydraulic plastic molding injection machine. I will need temperature control (PID + PWM), hydraulics speed control (PID + PWM), some timing, inputs, outputs etc. But, of course, I don't need XYZ positioning, G code, etc. from LinuxCNC. I think, I will need HAL and connect it to GUI.
Or is this wrong idea at beginning?

Yes, you can use HAL (with any hardware) without using LinuxCNCs
motion component.
