[Milsurplus] Three-phase equipment on single-phase power?

[R. Goff]

I hope I'm not beating a dead horse here-searched the archives and
couldn't find much discussion.  Trying to get a Navy WRT-2 transmitter
up and on the air and looking for advice/suggestions on the power
problem.

Originally the transmitter was set up for 115/220/440 3-phase delta input.

The HV PS uses three separate transformers wired delta-wye, going into
a three-phase full wave rectifier with 3B28s.

I'm thinking in this case (with the 3 transformers) I should be able
to separate the three wye-wired secondaries and re-wire the rectifiers
into three single-phase full waves in parallel.  I imagine I'll have
to increase the size of the filter caps to handle the increased ripple
and maybe even boost the primary voltage to make up for the lower
single-phase average.

All that still seems way easier than trying to come up with 3-phase
power! I looked at rotary converters and VFDs or a three-phase
generator-all have their downsides.

Any reason why it won't work?
Thanks,
