So, are you saying that you can make a subject appear in
focus on print if it is not in focus on the negative,
simply by changing the print size?

What is in focus on the neg is in focus,  and what's not
that's not.  Print away all you want,  there's no way
around it.  Of course for large enlargements you obviously
also have to enlarge the grain,  so you loose tonality,
but that has nothing to do with the DOF during exposure.

I think you are talking about film grain.  DOF has nothing
to do with the recording medium.  DOF is present even without
a neg or print.
