Huh?

You mean that the FGB-2 probe male docking adapter would be
replaced prior to launch with a hybrid male adapter?

Yes.

In that event, how would
FGB-2 dock with FGB-1?

It wouldn't - it would dock directly to Zvezda nadir.

Remember that there is a firm requirement to
have a module docked at FGB nadir prior to the arrival of Node 3.

There is a firm requirement to have three Soyuz/Progress/ATV docking
ports, but there are alternatives to FGB nadir for meeting that
requirement.

Once Node 3 is installed, if the MLM (FGB-2) is at Service Module
nadir, how does Soyuz or Progress dock with FGB Nadir???

They wouldn't, under this hypothetical assembly option. An additional
docking port would be required, either added to the FGB-2 or as a separate
docking module.
