Tom's right - the CVT would probably need to be several times more
massive than the B+ transformer.
This looks like a case for either a regulated B+ supply which can
compensate for changes in both mains voltage and load current (there
have been a few articles published - look in the archives of this list)
or else a high-voltage transmission system.
I remember visiting the station of a certain K2 who owned most of a hill
but lived only part-way up. He had a number of VHF shacks farther up the
hill, fed with mains via a pair of back-to-back pole transformers. The
HV wires were some kind of insulated cable, just draped over the
blueberry bushes... which the public were invited to come in and pick
from.
