IMO, IF Evgeni wants ... and is in top competitive form ... to compete in Sochi, the ISU will be more than "ready to consider restoration the amateur status" and will fall all over themselves to "take exceptional decision about restoration."
The ISU aren't complete fools, are they? A FULLY COMPETITIVE Plushenko in Sochi would mean nothing but huge $$$$$$$$ in so many ways. Nope, they are not that foolish.
Personally, I have serious doubts as to whether Plush can be competitive at the grand old age of 31 .. but, then, again, I (to my great shame) doubted that he'd be able to come back for Vancouver. Sorry, Plush.
I don't think Plush has an inkling of interest in competing in the intervening seasons; but, IF he's ready and able to compete in Sochi, oh yeah, he'll be there.
