Will editing the media white point tag in the source profile to match
that of the destination profile, make the absolute intent yield the
same results as the relative one?
Or besides editing the media white point tag, one should transform all
the colors in the colorimetric table via a Bradford or something like
that?

All the colors in an ICC profile are stored as white point relative, so looked at from the absolute intent point of view, the whole profile can be shifted by manipulating the white point in the profile.
