Who is the strongest character that gets knocked out by Shank's full power conqueror's haki release?

Joyboy's haki knocked out every marine at egghead except Kizaru, and Shank's haki is stated to be comparable to it. So at the very least, it's strong enough to knock out some of the vice Admirals. Do you think it would also knock out all the headliners on Kaido's crew? Maybe even PageOne? Do you think it would knock out the "army of rage" with guys like Bobin, Opera and Montd'or that BM sent after Luffy for beating Cracker?
