While I appreciate what you're going for, this wouldn't fly for countries imposing sanctions and the next immediate question from said countries to the repos would be "so how do you plan to stop this replication or penalize persons engaging in it?" Sanctions aren't really logical when you get down to it -- at face value they're supposed to put a specific stress to either motivate a population for change or impact the bottom line of targets enough to frustrate them into cooperation. In reality, the targets of sanctions typically are not affected, and those who are affected lack the ability to make meaningful change in the near future or even an extended future. Basically, even if you do something like this and replicate using a system outside of the intended mechanism, the sanction-ers' response is simply "why aren't you just banning them?" Call me cynical, but if the cost is bad publicity vs favor with the US government, it's not hard to see why a given company would choose favor. (I don't condone this, but I've lived in Russia for 6-ish years now as an ex-patriate -- it's...pretty clear that the sanctions affect no one they're intended to, and it's not like Russians haven't tried to change the status quo (they really have). But really, nothing has changed since the sanctions were imposed except a readjustment of prices and salaries)
