since the box seems to be unopened

Is there any Indication (no matter how small), that the box may appear to be tampered with?

Easily achieved on the sony boxes with a basic heat gun.

OP, if possible, please keep us updated, as im looking at doing this with a 1.5k sony lens in the near future. Highest value i have done this with is a $500 cpu. Replaced with a $10 one from ebay. Resealed virtually perfectly. Refund issued while item was in transit after a few days. Not heard back since. Unless they have some kind of protocol in place that flags high value items, over a certain amount, to be inspected extra carefully, I think you should be good to go. However seeing as they dont class a $500 CPU as a high value item, I dont see why they would treat a 2k mirror-less differently. So its worth a shot, in my opinion. Good luck, and please report back if possible :]
