I don't think the West would have guts enough to do that since it will mean (as experts say) a complete collapse of Russia's finacial system within a couple of days. The West is afraid that Putin will retaliate in god knows what way. So the policy of soft sanctional pressure will continue possibly coupled with a decision to supply Ukraine with weapons. But if the West opts for the latter I think the prudent thing would be to do it without any announcement urbi et orbi.
I wish you a smooth journey and uneventful stay in Moscow. Try to keep your head in the propaganda flurry you will experience there.
