[Amps] Paralleling diodes?

[SM0EJR 'Joe']

Hi!

I'm constructing a High Voltage PSU using a doubling-circuit.
But analyzing the circuit tells me that the current for the diodes will be
rather high...

I have lots of 500V/5 A diodes that I would like to use. Now comes the
question....
Can I parallel them?????

I would like to use 6 Diodes in 2 "legs" (in parallel) making up one beefy
diode.

Here follows a very crude schematic:


     Resistor -->Diode--->Diode  etc. -->Diode ----\
----/                                               ------
    \Resistor -->Diode--->Diode  etc. -->Diode ----/ 


Is an equalizing Series Resistor for each diode-leg useful or just an "old
truth"?
