Running the blockade doesn't necessarily require Russian cooperation in advance. All that's required is a minesweeper, and some commanders and captains with giant balls.
Run some ships under a NATO flag to Odessa, fill them up and run them back. Russia will bluster and threaten, but I doubt they'll actually do anything. Russia is not in a strong enough position to be able to escalate. I'm not anywhere close to sure of that, Putin is definitely not completely rational. I do think it's a risk worth taking.
