Nah man. I very much doubt that. Not because of the plausibility, but because of the plot. Itachi used it when he was an Edo while Sasuke had possession of his eyes.

If Sasuke unknowingly had said items, this probably would not have occurred and/or he would have discovered them by now. It's still possible however since Itachi did come in contact with Sasuke before his death (resembling the forehead tap).

I feel that Kishi made those items more unique to Itachi's character, as he made Itachi find them and not Orochimaru despite searching for said items for years.
