Wells,

Paralleling diodes is feasible, but do you really need more than the 350 to
550 ma most are rated for?

3 amp 1N5408s aren't very expensive, and a string of them totaling at least
twice the PIV they will experience would be more robust.

Most MOT diode blocks drop around 7 volts across them, so you can experiment
with paralleling them using a low voltage transformer (24-48 volts), drawing
a few hundred ma through the diodes, and see how low a series resistance you
can use to have fairly even current division between them.
