Atoms bouncing off each other collapses their waves.That doesn't even parse.

There's something you need to understand.

It has already been pointed out, but you have missed it.

Imagine making a grating with a gap between the "wires" that's a little bit smaller than the molecules you are using.

Classically, no particles will get through it.

QM and the uncertainty principle means that a few will. They will quantum tunnel through.

Here's the bit you don't understand.

If you take the grating and hammer it until the wires are squashed flat and there are no gaps so it becomes a metal foil then repeat the experiment...

More atoms will get through the foil even though it no longer has gaps in it. (In some circumstances)

Do you understand that?

The probability of tunneling is related to the thickness of the barrier.

Hammering it flat makes it thinner and so it's more likely that atoms will tunnel through.

Obviously, with the grating destroyed, there's no diffraction pattern.

And the (smaller number of) atoms that went through the grating before you hammered it flat would also show no clear diffraction pattern because, at that level, the atoms are not going through the gaps.

It's the same , classically, with light

You know the equation

d sin θ = λ

Where lambda is the wavelength and d is the spacing

you can rewrite that as

sin θ = λ /d

Well, if you make d smaller than lambda then you are trying to find an angle where sin theta is more than 1, but that's impossible.

Diffraction doesn't work if the wavelength is bigger than the grating's spacing.

And, returning to QM, a particle can't be "smaller" than the associated wavelength.

So, you can't sensibly calculate a diffraction pattern for the the experiment you have proposed.

So there's no way to say whether the particles would follow it or not.

And, as has been pointed out before, you also can't measure it because, in practice big things don't go through small holes.
