If you have a single power supply with multiple voltages yes. Otherwise to use different power supplies, i dont think so, and i wouldnt try it if i were you. Different power supplies can have different ground levels, and then your control logic may not be where it has to. You could tie the grounds together to ensure they are at same level, but then current may not sink balanced in grounds the same way they would if were separate. The current from both psu can get into only one ground, meaning can easily overrun one of them. To overcome that, could use two psus that are big enough, each rated higher than entire device consumption, but still personally i wouldnt try it. But its your decision to make of course.
