Regulation is improved by doing that.

Somewhat, but still not as solid as parallel primaries. I've seen
two separate transformers with the primaries in series and the
secondaries connected as a center tapped full wave bridge, and the
voltage bounced all over the place. it would have been even worse if
the transformers didn't saturate when the primary on that core went too
high. It was done by some fly by night TV shop back in the '70s. An
OEM replacement took care of multiple problems.
