There is an example of how to draw that diagonal stem at
  http://lsr.di.unimi.it/LSR/Item?id=505
but I also prefer the single-stem chord notation.

By default, LilyPond applies the usual rules for chords to this case,
and it works well.  The flat is printed left of the natural, so the
natural cannot be mistaken as canceling a double flat.

I leave these clusters printed as chords, and shift the flat a little
lower, so that the accidentals are staggered, and then I recognize it
as a chord of a second without hesitation.
