It seems to me that if the two hinges aren't both attached to the
lid such that the hinge pins are lined up (in 3 dimensions, which
means 6 degrees of freedom, though the plane of the surface you
are mounting the hinges on would remove one of those), you'll
still have problems.

Hinges typically have the barrel that you can align with the back
edge of the lid. That will keep the hinge pins on the same line.

No, I've tried that, and perhaps it's just me but there just isn't
enough accuracy gained by doing this. If the barrel is not 100%
aligned (by the slightest fraction of a degree) then that angle will
"grow" the error the further down the lid; the longer the lid, the
worse.

Are you leaving the entire hinge exposed? That would add a degree of
difficulty. Typically small box hinges are intended to be mortised.

I'm actualy replacing broken hinges with slightly larger ones. The mortice
is no more than a complete notch in the wood for the entire thickness of the
board, because it is so thin.
