Maybe you could get away with that for bold, but it probably wouldn't be
very good, and I don't think you could reasonably do it for italic.  When
a letter is slanted, its top is no longer at the same coordinates as
before; so if the accent was above the top of the letter before slanting,
it will no longer be above the top of the letter after slanting.

If your italics are really italics - with different shapes for some
letters - then the letters that have different shapes will need completely
new positions for the accents.  If your italics are fake ones, just
created by slanting the roman shapes, then it might be reasonable to apply
the same slanting transformation to the accent anchors and use the
results; but even then it wouldn't just be cutting and pasting.
