I think the only safe solution if you HAVE to parallel 2 PSUs is to use diodes on all the lines.

The 0.7v drop is an issue, but hopefully you can tweak the outputs just enough so it isn't a problem.

If I had the two PSUs handy, I'd try the diodes and see what I could get. It shouldn't hurt the PSU in any way I can think of currently. Can try it with a few fans as load and see what voltages you get.

If the lines are high, like the 13v mentioned before, resistors can help this. I had to resistor an old PSU due to a 5.89v output under load.
