The BBD BiLevel is narrower than a Superliner, so even with the steps
sticking out a few inches, there's no horizontal clearance issues on any
tracks where a Superliner fits--and even the Superliner doesn't fill the
full size allowed with Plate F (but it's bigger than Plate B/C/E), so
you could probably add them to a Superliner as well.

Worst case, you could make the steps retractable; that'd drive up the
maintenance cost a bit, but it'd still be cheaper than paying
round-the-clock wages for step box operators on every car.
