Wow, that's huge!
Although, I CAN think of a pretty simple way to do it. If you can find a
big enough 220V/120V isolation transformer, you could connect it to the
220V line and rectify the 120V output directly. It would only give you
about 170V, but that's within 10%. Or you could connect a few smaller
isolation transformers in parallel to boost the current.
These guys have some that might work.

Be very careful though and DON'T GET AUTOFORMERS! Extremely bad things
could happen since autoformers offer no isolation from the AC line.
