Hamon already has mind control properties. It's not out of the ordinary to assume that any passive mind manip from his semblance would be ignored entirely, if that is indeed how it functions.
My point about luck was to illustrate all the shitty situations Joseph found himself in, and has still managed to get through via his own quick thinking and abilities, even impossible ones. I don't see any way Qrow's semblance is really going to have him take the win. It's going to annoy Joseph and he'll feel like he can't do anything right, but again, he'll come out on top eventually, due to the fact that there are some things that can't be stopped via bad luck (like someone stabbing you) and that Qrow's semblance is merely chance, not a guarentee.
...
Anyways, we've gotten a bit off-topic. Weekly, why are you still using the buckshot argument? Joseph is in a fight against a sniper, he literally cannot hit him if he just keeps his distance. That doesn't mean he can't force Qrow to stop sniping, though. How?
The Joestar Secret Technique! My man decides to book it, non-stop running as far away from Qrow as he can. He's done it against another opponent he could not defeat, Kars. He's done it to a stand he had no idea on harming, Empress. He's going to run away from an explosive sniper, and that's final. He knows what he has to do, get to the city streets and lose him. Qrow is going to be forced to refrain from using his buckshot for fear of destroying property or endangering citizens, who are especially at risk because of his semblance. There's less room for something to go wrong if he decides to just stab Joseph, so that is exactly what he does.
Through this LIKELY if not expected course of action, Qrow will be forced to fight Joseph in hand-to-hand combat. He catches up, Joseph realises and lets him. They proceed to fight. For the sake of argument, Qrow is more skilled in fighting. He starts off throwing punches, kicks and other fancy blows from his sword all of which are able to connect, but not harm Joseph. Regardless, he is ragdolled around the streets rather amusingly.
Eventually, the old man is not having it. This has been the most embarassing day of his life, can his luck get any worse? He finally resorts to using his secret weapon: HAMON! He starts practicing his breathing in the middle of his beatdown, now making more of an attempt to block every blow rather than the important ones. Qrow's had about enough to, and activates his scythe in an attempt to just lob Joseph's head off. He does so and swings... but Joseph catches it! His prosthetic arm! He acknowledges that it's been a long time since he's used this, but activates the nail in the coffin for Qrow: Sendo Hamon Overdrive. He actively floods the scythe he's holding onto with dangerous amounts of hamon, something that normal people are unable to see, only commenting that the person seems glowing and full of life rather than witnessing the electricity.
Essentially charging Qrow like a battery through his own scythe, the drunk begins to lose his motor functions. Regardless of if he was undead or not, small amounts of hamon have been shown to steal bodily control from non-hamon users. Instead, he is being charged with a dangerous amount, shutting down major organs instead. This is the end for Qrow. Joseph follows up with another overdrive or punch to his opponents face, knocking them out.
