No, because you would NOT get seperation of the supplies.
If you hooked up the supplies to the 2 ac legs of a 4 diode full wave
bridge, the supplies would be connected through the two doides that make
up the negitive half of the bridge, only by using 2 diodes will you get
true isolation. All you need to do is isolate the positve outputs of the
supplies, the negitive can be wired together.

and then use one half for one amp, one half for the other? (I have
already opened the powersupplies up and tweaked their voltages a bit
(14.4 volts instead of 13.8)
