I am still not sure what you mean... The "box" is just a window in which
you look at an infinite (in size) system. It doesn't matter where you
look at it, the system is always the same. The "box" does not define
boundaries in the sense of boundary conditions, it is just a
visualization tool.

As Jan suggests, you can generate the objects outside the window. E.g.
you could put the sandpile cloud everywhere outside the box, if all
objects are translated by the same amount the result will be exactly the
same (even if the translation is a not a multiple of the box size).

if I don't miss something, you can put the mill half-way between two
periods (i.e. don't translate anything), it should not break.
