So I can parallel either diodes alone, or rectifier blocks to get
increased current capability? I understand about the cascade failure
if one should go.

A tiny amount of resistance in series with each diode will help equalize
currents among them.

But this is getting crazy. Bridges with 500 Amp peak capacity are
inexpensive enough not to have to cludge something together. I don't think
your transformer will deliver that.
