EXAFS fit will not tell apart. XANES analysis with or without LCA will.

Dear all,
While fitting EXAFS for tiny Pt nanoparticles, a simple question occurred to me. For these two scenarios: 1. All Pt atoms are coordinated to 3 O atoms and 3 Pt atoms each. 2. Half of the Pt atoms are coordinated to 6 O atoms and half to 6 Pt atoms.
If we fit only single-scattering paths, would it be possible to tell apart these two scenarios with EXAFS fitting? What about linear combination analysis of the XANES?
Thank you, Soyoung
