What would be the X-ray diffraction intensity of a ternary compound with one atom spatially fluctuating inside the octahedra?

If a ternary ABC2 compound with two sublattices, say BC4 and AC8, where B and C are at the center of tetrahedra and octahedra respectively, suppose if A atom is randomly fluctuating inside the AC8...
