You could always use a higher-wattage resistor and run all of the regulation leads through it to help cope with any difference in voltage between the PS's. I'd also put a small bipolar capacitor between all of the (+) regulation leads to further smooth any V ripple. Maybe some bipolar caps on the output leads, too.
