Dave,
Essentially all you are saying is the a 37mm round could hit a 38mm circle once every 20k tries.
Keep in mind that (I am discounting the Panther's muzzle brake here) that the orientations of the two gun tubes would have to match exactly including the elevations. The Panther's degree of depression would have to match the Greyhound's degree of elevation.
The 37mm round is 49% as big as the 75mm gun tube.
A .22 caliber bullet is 49% as big as the bore on a .45 caliber pistol. How many times do you think a guy shooting a .22 at a guy shooting a .45 is going to put one down the barrel of the .45?
Not 1 in 20k tries.

/Not being argumentative, just sayin'
A good pistol shooter will get more than half his .22 shots in the nr 10 circle of the target
board at 25 meters (more than 80 feet) when shooting single handed. That spot has a diameter which is something like 4 times that of the .45 so the hit area of the nr 10 circle
is 16 to maybe 20 times the area of the .45 muzzle.
I don't think that 1 out of 20 aimed shots would enter the .45 muzzle but maybe 1 in 100.
I have personally taken the cap of an ordinary small plastic coke bottle at 80 feet with a
.22 pistol held with both hands for more precision.
As a side note: Somewhere on the net there is an image of a T-55 or T-62 barrel with a
long silvery scrape along the side where an Israeli APFS-DS penetrator has forced its
way into the barrel and taken out the tank when it penetrated the breech.
The concerns about the barrels having to be aligned isn't so important since both guns
would be aiming roughly at each other at the interesting moment and if the smaller round
hits the opening at a few degrees off the perfect alignment it would enter sufficiently to be
diverted into the larger tube, even with the muzzle brake.
Here is another very unlikely event for which there is photographic evidence:
What are the chances of a machine gun from a kamikaze aircraft getting stuck in the
barrel of a 40 mm AA-gun on board a US battleship when the aircraft hits the side
of the ship? It has happened ...
As for the original question it would have to be very lucky shots for a 37 mm shell to be
able to penetrate 80 mm of armour sloped at 30 degrees. Maybe possibly if they
managed to hit some hatch or opening with less armour. I'm not saying it could
never happen but it would be highly unlikely.
